Mike Lee has in recent years become one of the Senate's most prolific social media posters, his presence seen in thousands of posts, often late at night, about politics. Fellow senators have grown accustomed to the Utah Republican's pugnacious online persona, mostly brushing it off in the name of collegiality.
That is, until this past week.
His posts, after the June 14 fatal shooting of a Minnesota lawmaker and her husband, incensed Lee's colleagues, particularly senators who were friends with the victims. It all added to the charged atmosphere in the Capitol as lawmakers once more confronted political violence in America.
As the Senate convened for the week, Sen. Tina Smith, D-Minn., marched past a crowd of reporters and headed toward the Senate floor: "I can't talk right now, I have to go find Sen. Lee."
Smith, whose name was listed in the suspected shooter's notebooks recovered by law enforcement officials, spoke to Lee for several minutes. The next day, Sen. Amy Klobuchar, D-Minn., did the same. By midday Tuesday, Lee had deleted his tweets.
