Congressional Republicans are rallying around Attorney General Jeff Sessions following a string of critical tweets from President Trump, and are calling for the president to take his issues with the former Alabama senator offline and behind closed doors.

“During the past twenty years that I have served with Jeff Sessions in the Senate, I have had the opportunity to know him well,” Sen. Richard Shelby, R-Ala., said Tuesday on Twitter. “Jeff Sessions is a man of integrity, loyalty, and extraordinary character. I join the people of Alabama in giving Jeff Sessions my deep respect and unwavering support.”
