Finally, a little Senate bipartisanship!

US Sens. Lindsey Graham (R-SC) and Corey Booker (D-NJ) joined forces Thursday to give accused crooked colleague Sen. Robert Menendez (D-NJ) a character-witness boost.

Graham and Booker took turns on the stand in federal court in Newark to tell jurors that Menendez is honest — really.

“A handshake from Bob is all you need,’’ Graham gushed. “He’s a very honest man and always keeps his word … he can push back against a lot of political pressure, which is hard in my business.”

Taking the stand after Graham, Booker testified that Menendez “has never let me down.

“Bob Menendez is trustworthy and honest; he doesn’t candy-coat things,” Booker said. “One of the best things about politics in the last four years is that I get to work with Bob Menendez.”

Menendez is charged with accepting gifts from a doctor pal, including flights on a private jet, in exchange for helping in an $8.9 million Medicare dispute and a stalled port security contract in the Dominican Republic.

His Senate colleagues’ testimonials came as his defense lawyers made a Hail Mary request for a mistrial, in protest over recent judicial rulings they said have hamstrung their case.

The rulings include the judge’s decision earlier Thursday to bar testimony by Marc Elias, the Hillary Clinton campaign lawyer who was recently outed for commissioning the controversial dossier filled with unsubstantiated salacious claims about President Trump.

The defense had hoped Elias would testify about giving Menendez advice on filling out Senate financial disclosure forms, which he is accused of doctoring to hide the bribes.

US District Judge William Walls found that such testimony would have improperly included Elias’ hearsay descriptions of Menendez’s side of the conversation.

The judge signaled before the lunch break that he’s not inclined to grant a mistrial.

“At this point, I’m not impressed by your argument that what I have done or not done so far warrants a mistrial,” Walls said, before the trial ended for the week.

Testimony resumes Monday. The judge did not say when he would rule on the mistrial request.
