Trump has a new chief of staff: Tea Party birther Mark Meadows.

With his choice, Trump tapped a lawmaker who was first elected in the post-Tea Party wave of 2012 and served as chairman of the Freedom Caucus. Meadows has been a key Trump ally since 2016 and the two reportedly talk frequently. During the impeachment battle, Trump and Meadows, who was instrumental in designing the president’s defense, talked several times a day.

Meadows also shares something else with the president, a past questioning of former President Barack Obama’s nationality. While campaigning in 2012, Meadows was asked if he would pursue an investigation to find out if Obama really is a citizen. “Yes,” Meadows responded. “If we do our job from a grassroots standpoint, we won’t have to worry about it. We’ll send him back home to Kenya or wherever it is.”
