President-elect Donald Trump announced on Tuesday that he will appoint South Dakota Gov. Kristi Noem to serve as secretary of the Department of Homeland Security (DHS) in his upcoming administration.

Noem, who was once considered a potential running mate for Trump, has served as governor of the Mount Rushmore State since 2019. Before becoming governor, Noem was South Dakota’s at-large congresswoman from 2011 to 2019.

The DHS oversees U.S. Customs and Border Protection, Immigration and Customs Enforcement, the U.S. Secret Service and the Federal Emergency Management Agency. Sources previously told Fox News Digital that Trump would select Noem to lead the DHS.

In a statement released on Tuesday night, the Trump transition team said the South Dakota governor has a ‘very strong’ track record on border security.

‘She was the first Governor to send National Guard Soldiers to help Texas fight the Biden Border Crisis, and they were sent a total of eight times,’ the statement reads. 

‘She will work closely with ‘Border Czar’ Tom Homan to secure the Border, and will guarantee that our American Homeland is secure from our adversaries.’

On X, Noem wrote that she was ‘honored and humbled’ by the appointment.

‘I look forward to working with Border Czar Tom Homan to make America SAFE again,’ the Republican wrote. ‘With Donald Trump, we will secure the border and restore safety to American communities so families will again have the opportunity to pursue the American Dream.’

Noem’s forthcoming appointment to the position came as one of many bombshell announcements on Tuesday. The Trump transition team also announced that Pete Hegseth will be nominated to serve as secretary of the Department of Defense and that Elon Musk and Vivek Ramaswamy will lead the new Department of Government Efficiency.

Speaking to ‘Your World’ host Neil Cavuto, Noem said last week that Trump has spoken to her personally about his focus ‘on big things.’

‘He knows he only has four years, and he wants to hit the ground running,’ Noem said. ‘And he said anybody that I want around me needs to be thinking big, too.’

Tensions were high among House Republicans on Tuesday with a group of GOP hardliners threatening to protest Speaker Mike Johnson’s leadership during the next day’s House GOP Conference leadership elections.

Three sources told Fox News Digital that members of the conservative House Freedom Caucus were exploring ways to show their discontent with House GOP leaders during the closed-door races to decide who will likely lead the majority next year.

Meanwhile, those threats sparked frustration among rank-and-file House Republicans, including one lawmaker who said such discussions were ‘just more stupid.’

The heart of the issue lies in proposed rule changes that the House GOP Conference will also vote on, including a measure pushed by some Republicans to punish colleagues who purposely sink their own party’s legislation on the House floor by stripping their committee assignments.

Johnson told Politico on Tuesday evening that he would not support ‘punitive’ measures against people who blockade the House floor, but sources signaled that would not be enough.

‘There’s a difference between saying, ‘I don’t support it’ and ‘I’m going to stop it.’ That’s a big difference,’ one source said. ‘His easy route is just to say, ‘All right, no rules changes. We’re just going to go forward.’’

Reports indicated earlier that Freedom Caucus members were looking for a candidate to challenge Johnson – something its chairman did not rule out.

‘Having two people in a race is kind of the norm,’ Chairman Andy Harris, R-Md., told reporters when asked if his group was putting up a candidate. ‘We can do this Soviet-style, or we can do it American-style.’

But no one candidate appeared to emerge as of Tuesday night, though Fox News Digital’s sources said conservatives could still coalesce around someone.

Instead, Johnson’s GOP critics could seek a recorded vote where they could either simply vote against his candidacy for speaker or write another name in via secret ballot, Fox News Digital was told.

The discord comes as President-elect Donald Trump plans to address House Republicans on Wednesday morning ahead of their leadership races, two other sources familiar with planning told Fox News Digital.

Several GOP lawmakers who spoke with Fox News Digital were frustrated that the public chaos that permeated the 118th Congress could once again rear its head – this time, when Republicans were poised to control all the levers of power in Washington.

‘Frankly, I am tired of the instigators. I am tired of the conflict for the sake of conflict-type nonsense that happened last session,’ Rep. Greg Murphy, R-N.C., told Fox News Digital.

Asked if lawmakers who help lead that charge should face consequences, Murphy said, ‘Absolutely. You can put that with an exclamation mark.’

Another GOP lawmaker said they were concerned about whether such a protest would lead to another messy House floor fight over the speakership, similar to the 15 rounds of voting ex-Speaker Kevin McCarthy, R-Calif., faced nearly two years ago.

‘What would worry me is if they’re willing to take that battle to the floor again. That’s where it doesn’t serve any kind of positive purpose at that point,’ that lawmaker said.

Rep. Ashley Hinson, R-Iowa, posted on X, ‘Enough is enough with the unserious political games – we have work to do.’

Others who have criticized Johnson in the past – like Reps. Marjorie Taylor Greene, R-Ga., and Anna Paulina Luna, R-Fla. – signaled little appetite for supporting a challenger against Johnson, particularly if Trump backs the speaker on Wednesday morning.

The Hill was first to report that House Freedom Caucus members were seeking a challenger to Johnson.

Elon Musk, who was selected by President-elect Donald Trump to head the Department of Government Efficiency (DOGE) with former Republican presidential candidate Vivek Ramaswamy, shared some insight on X on Tuesday into how the department will operate.

Musk said that the department will take suggestions and concerns from everyday Americans regarding how the government spends money.

‘Anytime the public thinks we are cutting something important or not cutting something wasteful, just let us know!’ Musk said in part in the X post.

Musk also said all the department’s actions ‘will be posted online for maximum transparency.’

‘We will also have a leaderboard for [the] most insanely dumb spending of your tax dollars. This will be both extremely tragic and extremely entertaining,’ he wrote.

When announcing the new department on Tuesday, Trump said its purpose will be to ‘dismantle government bureaucracy, slash excess regulations, cut wasteful expenditures, and restructure federal agencies.’

‘DOGE’ will advise and guide the administration by utilizing knowledge from outside of government and will partner with the White House and the Office of Management and Budget to ‘drive large scale structural reform.’

Musk and Ramaswamy, both of whom are successful entrepreneurs, have been adamant about their desires to cut unnecessary spending in order to reduce the government’s debt of at least $35 trillion.

‘This will send shockwaves through the system, and anyone involved in government waste, which is a lot of people!’ Musk said.

Ramswamy also said he and Musk ‘will not go gently’ shortly after Trump announced their new roles.

Musk and Ramaswamy are the latest additions to Trump’s administration after a busy few days loaded with appointments.

The latest include South Dakota Gov. Kristi Noem for Homeland Security secretary, Fox News’ Pete Hegseth for defense secretary, former Arkansas Gov. Mike Huckabee as ambassador to Israel, and John Ratcliffe for CIA director.

Just over a week after his sweeping election victory, former and future President Trump returns to the White House on Wednesday.

Trump is returning to 1600 Pennsylvania Ave., his first time back in nearly four years, at the invitation of the man he knocked out of the 2024 White House race: President Biden.

The two presidents will sit down in the Oval Office around 11 a.m. ET, according to the White House.

For Biden, who ended his re-election bid in July a month after his disastrous debate performance against Trump reignited questions over whether the 81-year-old president was physically and mentally up for another four years in the White House and sparked calls for him to drop out of the race, the meeting with his predecessor and now successor may be awkward.

Trump spent years verbally eviscerating Biden and his performance in the White House. And even after Biden ended his re-election bid, Trump continued to slam the president and his successor atop the Democrats’ 2024 ticket, Vice President Harris.

And Biden for a couple of years has labeled Trump a threat to the nation’s democracy.

But Biden, a traditionalist, wants to ensure a smooth transition between administrations.

‘I assured him that I’d direct my entire administration to work with his team,’ the president said of his call last week with Trump after the election when he made the invitation. 

Trump’s team, in an apparent change of tone toward Biden, said the president-elect ‘looks forward to the meeting.’

Biden’s offer to Trump to visit the White House was an invitation he himself was never accorded.

Four years ago, in the wake of his election defeat at the hands of Biden, Trump refused to concede and tried unsuccessfully to overturn the results.

Breaking with longstanding tradition, Trump didn’t invite Biden to the White House. And two weeks after the Jan. 6, 2021, riot at the U.S. Capitol by Trump supporters aiming to upend congressional certification of Biden’s Electoral College victory, Trump left Washington ahead of the presidential inauguration of his successor, becoming the first sitting president in more than a century to skip a successor’s inauguration.

‘President Biden’s decision to welcome President-elect Trump to the White House is a tribute to normalcy in the presidential transition process. What was denied to Joe Biden following his election is being restored to Biden’s credit,’ veteran political scientist Wayne Lesperance told Fox News.

Lesperance, the president of New Hampshire-based New England College, called the invitation by Biden ‘a remarkable gesture in that it legitimizes Trump’s return to power by the nation’s leading Democrat and, hopefully, will be met with a commitment to orderly transitions in the future.’

The meeting will be the first between Biden and Trump since they faced off in their one and only debate on June 27 in Atlanta. The two presidents, along with Harris and Trump’s running mate, now-Vice President-elect Sen. JD Vance, stood next to each other on Sept. 11 in New York City’s Lower Manhattan at ceremonies for the 23rd anniversary of the 9/11 terrorist attacks.

This will be Trump’s second meeting at the White House with a departing president.

Eight years ago, after defeating Democrat nominee Hillary Clinton, Trump sat down at the White House with President Obama, who was finishing up his second term.

‘We now are going to want to do everything we can to help you succeed. Because, if you succeed, then the country succeeds,’ Obama told Trump at the time.

While a tradition, the meeting between the incoming and outgoing presidents is not mandated.

A big question mark heading into the meeting: Will the vice president join Biden and Trump for any portion of the gathering?

Harris phoned Trump last week and congratulated him on his victory over her.

The last time a sitting vice president ran for president and lost was 24 years ago when then-Vice President Al Gore narrowly lost to then-Texas Gov. George W. Bush.

Gore ended up joining Bush and outgoing President Clinton in the Oval Office for what was said to be a very awkward meeting.
