Republicans in Quandary Over Vote on Loretta Lynch

Senate Republicans do not want to be held responsible for rejecting the historic nomination of Loretta E. Lynch, the first African-American woman picked to be attorney general. But they also are in no hurry to see her confirmed because of her defense of President Obama’s immigration policies.

That contradiction showed signs of being self defeating on Friday, when a visibly emotional Mr. Obama elevated the issue at a news conference by saying “Enough! Enough!” about the record delay, after a call the day before from Jeb Bush, one of the top Republican presidential prospects, to confirm Ms. Lynch.
