House Democrats have invited former CIA director and frequent Trump critic John Brennan to brief them on the situation in Iran.

Brennan is scheduled to speak at the party‘s weekly caucus meeting Tuesday, according to the Associated Press. Wendy Sherman, a former State Department official who helped negotiate the Iran nuclear deal under President Barack Obama, was also invited.

The meeting will take place the same day Trump administration officials will update lawmakers on escalating tensions between the two countries. Democrats will likely attend both briefings.
