Sen. Markwayne Mullin, R-Okla., expressed confidence in Pete Hegseth’s defense secretary nomination despite opposition from moderate Republicans. Hegseth is expected to undergo a final confirmation vote on Friday evening. Müller estimated that 50 to 52 Republicans, including all the Democrats and several moderate Republicans from Alaska and Maine, will support Hegseth’s nomination, which means opposition from more moderate Republicans could sway the outcome of the vote.
