Democratic Senate nominee Amy McGrath has gone on the offensive after her narrow primary win.

She challenged Senate Majority Leader Mitch McConnell to disclose what he knows about intelligence assessments suggesting Russia offered bounties for killing U.S. troops in Afghanistan.

McGrath’s attack comes a day after she defeated Charles Booker in Kentucky’s primary election.

In a Senate speech Wednesday, McConnell warned of Russian efforts to undermine U.S. interests in the Middle East.

“The United States needs to prioritize defense resources, maintain a sufficient regional military presence and continue to impose serious consequences on those who threaten us and our allies — like our strikes in Syria and Afghanistan against ISIS, the Taliban and Russian mercenary forces that threatened our partners,” McConnell said.

McGrath’s attack is just the beginning to what’s expected to be a big-spending, hard-fought fall campaign in Kentucky as McConnell seeks a seventh term.

When asked to comment on the McGrath attack, McConnell’s campaign referred to the senator’s previous remarks on the matter in pushing back against her claim that he’s being passive in the face of the intelligence assessments.
