Linda McMahon is leaving her role in the Trump administration.

Politico first reported today that McMahon is stepping down as the head of the Small Business Administration. She will become the chair of the America First Action super PAC, which Politico noted officials "view as a key plank" in Trump's reelection campaign and raising money for it.

The official announcement of McMahon's resignation could come as soon as today.

McMahon had been part of Trump's cabinet since the beginning of the administration. It was announced in December 2016 that she had been chosen to lead the Small Business Administration, and the Senate voted to confirm her in February 2017.

In November, it was reported that McMahon was a favorite to replace Wilbur Ross as Secretary of Commerce if Ross was removed from that role.

McMahon was a significant financial contributor to Trump's first presidential campaign.

McMahon had unsuccessful Senate campaigns in 2010 and 2012. She was the Republican candidate for office both times but lost to Democrats Richard Blumenthal and Chris Murphy in the respective general elections.
