Rep. Andy Barr, R-Ky., has launched his first negative campaign ad against Democratic nominee Amy McGrath in the 6th Congressional District race.

Barr calls McGrath a "radical progressive who will serve as a rubber stamp for the Democrats' agenda." He also claims McGrath is "too liberal for Kentucky."

The 30-second spot mostly uses quotes from McGrath where she says she is a feminist, progressive and pro-choice.

It would later use a soundbite where she says she voted for former President Barack Obama twice.

The last soundbite featured a clip from WKYT's Kentucky Newsmakers, where host Bill Bryant asked if McGrath supported building a wall on the Mexican border. She called the proposal "absolutely stupid."

"This is a very close race, it's a tight race, it's going to be an aggressive race, from the heat of summer now through election day," said Bryant.

McGrath would reply to the ad on Twitter, saying Barr has no record to run on while touting her experience as a combat fighter pilot. McGrath also issued a statement that said,"...apparently the best they’ve got on me is that I’m a Democrat. (That fact will actually be on the ballot.)"
