Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE (R-Ky.) is going after his Democratic opponent over her attack ads in a new ad of his own.

In an ad set to air Wednesday and shared exclusively with The Hill, McConnell touts his work passing a $2.2 trillion coronavirus relief package and hits Democrat Amy McGrath for her ads against him.

“Amy McGrath attacks Mitch McConnell for leading passage of the biggest economic rescue in American history. But while McGrath attacks, Mitch is working across the aisle to get hundreds of millions in federal dollars for Kentucky’s hospitals,” a narrator says. “McGrath attacks. Mitch McConnell leads.”

McConnell’s campaign did not say how much money went into the ad but said it was a "substantial statewide buy."

The Kentucky Republican was involved in negotiations to pass a $2.2 trillion relief package that ultimately passed the Senate in a 96-0 vote. The package, which President Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE signed into law, beefs up unemployment insurance for four months, provides checks directly to Americans making up to $99,000 and provides billions of dollars to hospitals and industries impacted by the outbreak, among other things.

The Senate is currently squabbling over additional funding to aid small businesses.

The ad is the latest salvo in an escalating exchange between McConnell and McGrath in Kentucky’s increasingly expensive Senate race.

McConnell released a video last month accusing McGrath of “spending millions on false, partisan attacks,” a clip that followed broadsides from the Democrat hammering McConnell for leaving Washington on March 12 to attend a ceremonial event in Louisville.

"That's right, he shut down the Senate in the middle of a pandemic and disappeared," McGrath said in a radio spot.

“The contrast between Mitch McConnell’s leadership for Kentucky and Amy McGrath’s lies to Kentuckians could not be starker,” Kevin Golden, McConnell’s campaign manager, fired back in a statement to The Hill.

“Senator McConnell is working nonstop to help our hospitals get needed funding, bring folks back home from overseas, and secure billions of dollars of coronavirus relief aid for Kentucky. Meanwhile, McGrath is airing false, negative ads and cheering on radical liberal politicians like Nancy Pelosi Nancy PelosiPelosi: Ginsburg successor must uphold commitment to 'equality, opportunity and justice for all' Bipartisan praise pours in after Ginsburg's death Pelosi orders Capitol flags at half-staff to honor Ginsburg MORE and Chuck Schumer Chuck SchumerPelosi orders Capitol flags at half-staff to honor Ginsburg Ginsburg in statement before her death said she wished not to be replaced until next president is sworn in Democrats call for NRA Foundation to be prohibited from receiving donations from federal employees MORE who shamelessly play games with the health and economic well-being of Americans.”

The race between McConnell and McGrath is expected to be an expensive battle for the Kentucky Senate seat as each candidate raises massive sums of money that could fuel further ads. The Cook Political Report, a nonpartisan election handicapper, rates the race as likely Republican.
