A growing number of senators have privately signaled that they are not inclined to vote to confirm Pete Hegseth as President-elect Donald Trump's next defense secretary, leading Trump's advisers to begin discussing who may be a viable replacement, sources familiar with the matter told ABC News.

       Sources tell ABC News that at least six senators have privately indicated that they don't intend to vote for Hegseth amid the growing allegations about his mistreatment of women.

       While Trump and his advisers have privately said the president-elect backs Hegseth and wants him to "keep fighting," sources familiar with private discussions tell ABC News that a growing list of replacements is emerging to replace him. Those include Iowa Sen. Joni Ernst, Florida Gov. Ron DeSantis, Tennessee Sen. Bill Hagerty and Florida Rep. Mike Waltz, whom Trump has already tapped to be national security adviser.

       The visit came after a report in The New Yorker that Hegseth was forced to step down from two veteran nonprofit groups -- Veterans for Freedom and Concerned Veterans for America -- amid accusations of financial mismanagement, sexist behavior and other disqualifying behavior.

       ABC News has not independently confirmed the magazine's account. Hegseth's attorney, Tim Parlatore, told The New Yorker the claims were "outlandish."
