Trump Small Business Administrator Linda McMahon expected to resign her post, sources say

McMahon, a former professional wrestling exec, will likely help Trump in 2020.

McMahon -- a wealthy former professional wresting executive and major booster of Trump's during the 2016 campaign -- is likely to help the Trump campaign with the 2020 fundraising efforts, sources said.

The White House didn't respond to a request for comment on McMahon's plans. She was one of the more behind-the-scenes figures in Trump's cabinet.
