Ensign was head of the Republican Policy Committee, the fourth-ranking Republican position in the Senate. Senate Minority Leader Mitch McConnell released this statement:
"He's accepted responsibility for his actions and apologized to his family and constituents. He offered, and I accepted, his resignation as chairman of the Policy Committee," Senate Minority Leader Mitch McConnell (R-Ky.) said in a statement just issued.
Update: Will Thune get the gig? He's currently serving as Republican Conference vice-chair, the fifth-ranking position in the Senate.
