Trump transition live updates: Johnson says he, Trump didn't discuss Gaetz Ethics Committee report

To replace Florida Rep. Mike Waltz in the U.S. House following his selection to serve as Trump's national security adviser, state statute requires Gov. Ron DeSantis to call for a special primary and then a special election in Florida.

The special elections to fill the House seat differ from Florida's way of filling Senate seats. State law mandates that DeSantis appoint an individual to fill any Senate vacancy.

Waltz currently represents Florida's solidly red 6th Congressional District, one that hasn't been represented by a Democrat since 1989. DeSantis himself was the congressmember for the northeastern Florida seat ahead of Waltz.

ABC News has not yet reported a projection for who will have control of the House, but Waltz's impending vacancy could impact Republicans' numbers as they head toward a GOP "trifecta" in Washington.

President Elect Donald Trump has announced former Gov. of Arkansas Mike Huckabee as the United States Ambassador to Israel.

"Mike has been a great public servant, Governor, and Leader in Faith for many years," Trump said in a statement. "He loves Israel, and the people of Israel, and likewise, the people of Israel love him. Mike will work tirelessly to bring about Peace in the Middle East!"

The role, which will need to be confirmed by the Senate, will be a key appointment as tensions remain high in the Middle East.

President-elect Donald Trump's newly picked "border czar" Tom Homan addressed his forthcoming deportation plan and state leaders who have objected to sweeping immigration policies.

During an appearance on Fox News on Monday, Homan issued a warning to so-called "sanctuary" states and cities to "get the hell out of the way" of the Trump administration's mass deportation plans.

"I saw today numerous governors from sanctuary states saying they're going to step in the way. They better get the hell out of the way. Either you help us or get the hell out of the way, because ICE is going to do their job," he warned, referring to the U.S. Immigration and Customs Enforcement, where he formerly served as director.

"I'll double the workforce in that sanctuary city. We're going to do our job despite the politics. We're doing it. So get used to it, because we're coming," Homan said.

When asked if he plans to deport American citizens, Homan said, "President Trump has made it clear we will prioritize public safety threats and national security threats first, and that's how the focus would be."

President-elect Donald Trump is naming cabinet members and adding other key positions to his administration.

These team members will have a direct impact on implementing Trump's policies in his second term.
