WASHINGTON — Loretta Lynch has found an unlikely ally — Jeb Bush.

The Brooklyn US attorney, whose attorney general nomination has been stalled for months in the Republican-controlled Senate, is getting a helping hand from the former Florida governor and probable GOP presidential candidate.

“I think that presidents have the right to pick their team,” Bush said while campaigning in New Hampshire Thursday.

Nominated in November to succeed Eric Holder, Lynch has been awaiting a confirmation vote by the Senate for 161 days — an unusually long time for a president’s cabinet secretary.

Bush tried to convince fellow Republicans to get moving on Lynch by pointing out the status quo isn’t acceptable.

“The longer it takes to confirm her, the longer Eric Holder stays as attorney general,” he said.

Republicans have had a contentious relationship with Holder, accusing him of politicizing the Attorney General’s Office.

President Obama, showing signs of frustration Friday, also called on the Senate to end the blockade of Lynch, a Harvard Law School graduate.

“What are we doing here?” Obama said at the White House. “I have to say, there are times when the dysfunction in the Senate goes too far.”

Senate Minority Leader Harry Reid is threatening to “force a vote” on Lynch if Republicans don’t act soon.

While many Republicans speak highly of Lynch’s qualifications, they protest her defense of Obama’s unilateral actions on immigration.

Sen. Majority Leader Mitch McConnell has also tied her nomination to approval of an anti-human-trafficking bill. Democrats are upset the bill includes language that would prohibit fines paid to a crime victim’s compensation fund from being used for abortions for victims of sex trafficking.

McConnell has insisted Lynch won’t come up for a vote until he wins enough Democratic support for the trafficking bill.

But he also said he’s optimistic the logjam will be broken next week, allowing the Senate to then move on to Lynch.
