It’s looking more likely Texas Sen. John Cornyn, R-Texas, will be the number two among Senate Republicans. Roll Call reports Sen. Richard Burr, R-North Carolina, is dropping his bid for Minority Whip.

“In recent weeks, I have come to the realization that the difficult and time-consuming nature of the policy issues I am invested in is not always consistent with a position in leadership. I have introduced many pieces of legislation, including Medicare and Medicaid reform proposals, and I intend to work vigorously to see them enacted. These efforts require serious attention, and they simply cannot be pursued with the focus they demand while also serving as a member of leadership." Burr said in a statement to Roll Call.

Cornyn currently serves as chairman of the National Republican Senatorial Committee.
