Senate Minority Leader Mitch McConnell (R-Ky.) blasted a Democratic super PAC on Saturday night for mocking the Chinese ethnicity of his wife, former U.S. Labor Secretary Elaine Chao, with a Valentine's Day tweet.

“They will not get away with attacking my wife in this campaign,” McConnell told about 100

supporters at a Republican dinner in Winchester, Ky., according to the Associated Press.

The super PAC, Progress Kentucky, tweeted on Feb. 14: "This woman has the ear of @mcconnellpress — she's his #wife. May explain why your job moved to #China!…"

At the dinner, AP reported, McConnell called the tweets racial slurs and “the ultimate outrage” and went on to defend Chao, who was born in Taiwan and moved to the United States as an 8-year-old with her family aboard a freight ship. “Elaine Chao is just as much an American as any of the rest of them,” McConnell said. “In fact, she had to go through a lot more to become an American.”
