Nevada Republican senator John Ensign is reportedly set to resign today. Here's the Las Vegas Sun:
At first he stood firm: the embattled Sen. John Ensign saying that, despite investigations into his conduct, he would stand for re-election. And then, just last month, he said he would complete his term, but not seek re-election.
And Thursday he packed it in. Saying the personal cost of staying in office was too much to bear, the man who once was considered possible presidential material announced his resignation, effective May 3.
Ensign's resignation will mean that his replacement will be appointed by Nevada Republican governor Brian Sandoval. It's widely expected that Sandoval will select Congressman Dean Heller to serve out the remainder of Ensign's term.
