Senate Republican Leader Mitch McConnell (Ky.) on Thursday accused President Obama and his advisers of using dirty tactics that demean the presidency.

The normally reserved leader delivered one of his most blistering attacks ever against Obama at the annual Conservative Political Action Conference (CPAC) conference.

“The White House and its lieutenants have made an art form out of the orchestrated attack. They’ve shown they’ll go after anybody or any organization they think is standing in their way,” he said.
