Local activist Justin Jones is challenging Democratic Congressman Jim Cooper for his seat in the U.S. House of Representatives.

According to Federal Election Commission documents, Jones made his candidacy official Monday.

Jones’ announcement comes months after some Democrats have been criticizing Cooper for not being progressive enough.

Local political groups said Cooper has not supported the Green New Deal or Medicare for All. They have also criticized Cooper’s initial resistance to the impeachment inquiry into President Donald Trump.

Jones is perhaps best known for protesting the bust of Confederate General Nathan Bedford Forrest. He was banned from the Tennessee Capitol after allegedly throwing a cup with liquid at former Speaker of the House Glen Casada.

Jones was later charged with assault.

He did not return multiple requests for comment Monday night.

Meanwhile, Cooper says he welcomes the competition.

“I like Justin and I welcome the competition from him or anyone,” Cooper told WPLN in a statement. “Competition is good.”
