The high-ranking House of Representatives Republican will testify Tuesday on Capitol Hill during a confirmation hearing for the United Nations ambassadorship during the second administration of President Donald Trump.

A key Republican has announced that she will vote to confirm Pete Hegseth, likely solidifying his chances to become the next Secretary of Defense. Iowa GOP Sen. Joni Ernest declared that she will be voting to confirm Hegseth, a crucial endorsement for a nomination that seemed to be on shaky ground a few weeks ago.

Sen. Markwayne Mullin (R-OK) previewed Senate action in anticipation of Pete Hegseth’s confirmation to be defense secretary, in addition to what is ahead this week for the other confirmation hearings for President Donald Trump’s new administration.

David Axelrod said Pennsylvania Senator John Fetterman could be among those who will support some of Trump's Cabinet picks.
