President Trump on Monday sympathized with his former chief strategist, Stephen Bannon, who has launched a self-described “war” on the Republican establishment.

“There are some Republicans, frankly, that should ashamed of themselves,” Trump told reporters during a Cabinet meeting. “So I can understand fully how Steve Bannon feels.”

Bannon has promised to back primary challenges against any Senate Republican who opposes Trump.

The president stopped short of explicitly endorsing that effort, but made it clear it is GOP lawmakers — and not him — who should receive the blame for their stalled agenda.
