FBI Releases Photos of Man Wanted for Questioning in 'Separate Incident,' Not Officer's Slaying

House Formally Introduces Article of Impeachment Against Trump, Cites 'Incitement of Insurrection'

Following last week's coup attempt at the U.S. Capitol, Democrats are looking to impeach Trump for the second time

The FBI has released photos of a man who attended Wednesday's pro-Trump rally and is wanted for questioning.

Senator Bill Cassidy, a Republican from Louisiana, initially posted the photos on his Twitter account, saying the man is wanted for questioning in connection with the slaying of U.S. Capitol Police Officer Brian Sicknick. But later, he walked back the claim, writing on Twitter, "Capitol Police has informed me the individual in my previous tweet is a person of interest, but for a separate incident that occurred at the Capitol on Jan 6th. Deleted tweet to prevent further confusion."

The photos show the unidentified man in a navy beanie with "CFD" on the front, wearing a flannel shirt, black backpack and cargo pants.

Nobody has been arrested or identified as a person of interest in the slaying of Sicknick, 42, who died at 9:30 p.m. Thursday from injuries he sustained "while physically engaging with protesters" at the riots, the USCP said in a statement. Law enforcement officials have told multiple outlets, including the Associated Press, that Sicknick was hit with a fire extinguisher.

"The entire USCP Department expresses its deepest sympathies to Officer Sicknick's family and friends on their loss, and mourns the loss of a friend and colleague," the USCP said in its statement.

The officer's death marked the fifth fatality in connection with the riots, in which a large group of pro-Trump supporters stormed the Capitol building as lawmakers gathered to certify Electoral College votes for President-elect Joe Biden.

According to the Capitol Police, over 50 officers from the department and Metropolitan Police Department sustained injuries, while several requiring hospitalization.

"The violent attack on the U.S. Capitol was unlike any I have ever experienced in my 30 years in law enforcement here in Washington, D.C.," Capitol Police Chief Steven Sund, who resigned from his post on Thursday, said in a previous statement. "Make no mistake – these mass riots were not First Amendment activities; they were criminal riotous behavior."
