Wednesday's meeting comes as the Republican Party is slated to take power of not only the White House but also the Senate, after a national shift to the right in the Nov. 5 elections powered GOP candidates to flip several Democrat-held held seats.

While NBC has not made an official call on which party will control the House in the next Congress, Republicans appear more likely to keep their majority.

House Republicans are scheduled to hold leadership elections behind closed doors on Wednesday. They are expected to nominate Mike Johnson, R-La., to continue as Speaker of the House in the 119th Congress.

Trump on Wednesday is also slated to meet with President Joe Biden at the White House.

The meeting, a gesture that bolsters the tradition of a peaceful transfer of power, did not occur when Biden beat then-President Trump in the 2020 election. Instead, Trump refused to concede the race and sought to overturn his Electoral College loss.

Vice President Kamala Harris, the Democratic nominee in the 2024 race, conceded on the day after the election.

Trump's entourage for Wednesday's trip will not include former first lady Melania Trump. An official X account representing her office confirmed her absence, but wrote that "Her husband's return to the Oval Office to commence the transition process is encouraging, and she wishes him great success."

The post, without adding specific details, added, "In this instance, several unnamed sources in the media continue to provide false, misleading, and inaccurate information. Be discerning with your source of news."
