Mike Pompeo is leveraging relationships with House Republicans to stay front and center with GOP voters as the former secretary of state mulls a 2024 presidential bid.

On Wednesday, Pompeo joined the Republican Study Committee, a caucus of House conservatives, to promote legislation cracking down on Iran’s nuclear weapons program. The news conference, in the shadow of the United States Capitol, attracted liberal Code Pink protesters who used a bullhorn to interrupt the former secretary’s comments and advocate for President Joe Biden’s bid for Washington to rejoin the Iran deal vacated by former President Donald Trump.
