Sen. Mike Lee files formal legislation calling for the investigation of a prominent Trump critic

One of Utah’s most faithful supporters of Donald Trump, Sen. Mike Lee, announced Tuesday that he is introducing legislation calling for an investigation into one of the president’s most prominent critics.

The resolution comes in response to a photo shared on Instagram by former FBI Director James Comey. The image portrayed seashells arranged to say, “86 47,″ and was accompanied by the caption, “Cool shell formation on my beach walk.”

In his current term, Trump is the 47th president, and the number “86″ is used in a variety of ways. Employees at bars and people affiliated with the military will often say it in reference to someone or something being thrown out, but in some contexts, the digits are used as slang for killing a person.

The same day he posted the photo, Comey deleted it, writing, “I didn’t realize some folks associate those numbers with violence. It never occurred to me but I oppose violence of any kind so I took the post down.”

“For the former FBI director to be amplifying threats against the president of the United States is disgraceful,” Lee said in a news release announcing the resolution. “President Trump has been targeted in two assassination attempts and wounded in one, which killed Corey Comperatore. Congress should unite to condemn Jim Comey in the strongest terms.”

The resolution’s title accuses Comey of “inciting violence against President Donald J. Trump,” and its text characterizes the post as “[issuing] a call for violence.” It also says the former FBI head “exhibits a clear desire to undermine President Trump” and follows a similar resolution introduced by a pair of House Republicans last month.
