Mitch McConnell will return to the Senate next week, more than a month after concussion

Senate Republican Leader Mitch McConnell is returning to work Monday, more than a month after he was hospitalized for a concussion after a fall, he said on his Twitter account.

McConnell said Thursday he would return to the U.S. Senate next week. He was released from the hospital a few days after his fall, but underwent rehabilitation, which could have lasted up to two weeks, a source familiar with his condition previously told USA TODAY.

"I am looking forward to returning to the Senate on Monday. We've got important business to tackle and big fights to win for Kentuckians and the American people," McConnell tweeted.

McConnell stayed in touch via text message with the No. 2 Senate Republican, Minority Whip John Thune, R-S.D., but they had not spoken directly.

The announcement comes four days after the shooting in Louisville's Old National Bank and the GOP leader said he and his wife, Elaine Chao, were sending prayers to the victims and their families. He also praised the work done by the Louisville Metro Police Department.

McConnell was attending a dinner at the Waldorf Astoria in Washington D.C. on March 8 and hit his head after he tripped. He was taken to the hospital in an ambulance.
