Trump transition live updates: Ethics Committee expected to meet on Gaetz: Sources

The National Guardsman who in 2021 pegged Pete Hegseth as a potential "insider threat" clarified in an interview with ABC News that his complaint targeted a "Deus Vult" tattoo on the Fox News host's arm, not a cross on his chest, as Hegseth has repeatedly claimed.

As Reuters and The Associated Press first reported, Sgt. DeRicko Gaither sent an image of the "Deus Vult" tattoo to Maj. Gen. William Walker shortly before President Joe Biden's inauguration. The phrase, which translates to "God wills it," has since been co-opted by white nationalist groups.

"This information is quite disturbing, sir," Gaither wrote in the email to Walker, who has not responded to ABC News' request for comment. "This falls along the lines of (an) Insider Threat."

Hegseth -- Trump's pick for defense secretary -- claimed in his book, "The War on Warriors," that he was removed from service ahead of Biden's inauguration because fellow servicemembers had flagged a tattoo of the Jerusalem Cross on his chest as a white nationalist symbol.

But Gaither clarified in a text message to ABC News that his complaint targeted the "Deus Vult" tattoo, despite "the narrative that has been out there."

"Just so we are clear. This has NOTHING to do with the Jerusalem Cross tattoo on his chest," Gaither said. "This has everything to do with the 'DEUS VULT' Tattoo on his inner bicep."

Gaither, who confirmed the contents of his complaint to ABC News, emphasized that "this wasn't then and isn't now a personal attack towards Pete Hegseth."

"The information received and [the] email sent on January 14th was the protocol that had to be followed because of the position assignment that I was assigned to," explained Gaither, who was at the time assigned as the Guards' head of security. "The protocol was followed and would be followed again if this issue involved any other service member, myself included."

Hegseth fired back at the initial coverage of this matter in the AP by claiming it was "Anti-Christian bigotry."

"They can target me -- I don’t give a damn -- but this type of targeting of Christians, conservatives, patriots and everyday Americans will stop on DAY ONE at DJT's DoD," Hegseth wrote on social media on Friday.

Incoming "border czar" Tom Homan said Monday that Trump's new administration is already working on a plan to deport undocumented immigrants and that he's headed to Mar-a-Lago this week "to put the final touches" on it.

Speaking on Fox News’ America Reports, Homan reiterated his plan to "take the handcuffs of ICE" and ramp up arrests.

"ICE knows what they're looking for. They just never go arrest them, because Secretary Mayorkas has told them [to] tone down the arrests,” Homan said.

Homan also repeated his claim that ICE will "arrest the bad guys first." He said that under the Biden administration, the removal of "criminal aliens" has decreased 74%. ABC News has not independently verified the accuracy of that claim.

Homan acknowledged during the interview that a mass deportation plan will require significant resources and that he doesn't know what the current ICE and Customs and Border Protection budgets are, though added that Trump is "committed" to getting the funding for his plan.

Caroline Kennedy weighed in on her cousin Robert F. Kennedy, Jr.'s views on vaccines during remarks on Monday after he was announced as the nominee for Health and Human Services secretary.

"I think Bobby Kennedy's views on vaccines are dangerous, but I don't think that most Americans share them. So we'll just have to wait and see what happens," she said at the National Press Club of Australia.

"You know, I grew up with him," she added. "So, I have known all this for a long time and others are just getting to know him."

Kennedy added that her uncle, Sen. Ted Kennedy, had fought for affordable health care, and that her family was proud of President Barack Obama signing the Affordable Care Act, which she said was built on Sen. Kennedy's work.

"I would say that our family is united in terms of our support for the public health sector and infrastructure and has greatest admiration for the medical profession in our country, and Bobby Kennedy has got a different set of views," Caroline Kennedy said.
