Former Sen. Jim DeMint is expected to be ousted from his role as president of the conservative Heritage Foundation, according to multiple reports.

DeMint had been criticized for moving the think tank toward a more combative approach, Politico reported. He had also moved to align the organization closer toward President Donald Trump. 

A GOP operative who works closely with Heritage told Politico that more changes beyond DeMint are expected.

“There’s massive turmoil over there right now,” the operative told Politico.

DeMint, one of the most stalwart conservatives in Congress, stepped down from the Senate in late 2012 and was succeeded by Sen. Tim Scott.
