Sen. Mitch McConnell’s campaign on Saturday tweeted out a photo showing mock tombstones with the names of former Supreme Court nominee Merrick Garland, socialism and the senator’s Democratic opponent.

His opponent in the 2020 Senate race, Amy McGrath, wasn’t exactly pleased, and she noted that the tweet was posted shortly after a mass shooting in El Paso, Texas .

Hours after the El Paso shooting, Mitch McConnell proudly tweeted this photo. I find it so troubling that our politics have become so nasty and personal that the Senate Majority Leader thinks it's appropriate to use imagery of the death of a political opponent (me) as messaging. pic.twitter.com/2x5kO5jwPi

It's symptomatic of what is wrong with our system. I'm fine with the ordinary rough and tumble of politics, but this strikes me as beyond the pale.

Kevin Golden, the campaign manager for McConnell, wouldn’t comment when HuffPost asked whether the post was poorly timed. Instead, he said McGrath was being disingenuous in her response to the photo, which he said was based on a political cartoon printed in the Louisville Courier-Journal.

“Our supporters built an homage to the Courier Journal cartoon at Fancy Farm and we posted their work,” he wrote in an email. “Amy McGrath has tweeted this very cartoon several times and it’s shameful that she’s pretending not to know exactly what it is referencing in order to politicize a tragedy.”

This is the cartoon Golden was referring to:
