As controversy continues to cloud some of Donald Trump's Cabinet picks, his team has a sharp warning for Republicans who don't fall in line, ABC's Jonathan Karl reports.

Summary

President-elect Donald Trump’s team warned Republican lawmakers to support his controversial Cabinet picks or risk facing primary challenges funded by Elon Musk.

Amid scrutiny over nominees like Matt Gaetz for attorney general and Pete Hegseth for defense secretary, Trump insisted the president determines the Cabinet.

Resistance has grown among Senate Republicans, including Sen. Thom Tillis, opposing “recess appointments” to bypass confirmation.

Senators like Josh Hawley and Mitch McConnell emphasized the need for proper constitutional vetting of nominees despite Trump’s pressure tactics.
