Convicted tax cheat Michael Grimm huddled with President Trump’s former chief strategist Steven Bannon in D.C. Wednesday in a bid to reclaim his old congressional seat and oust his successor, Republican Rep. Dan Donovan.

Grimm’s campaign spokesman Michael Caputo released a photo of the ex-congressman with Bannon in a tweet that said, `Game on#MAGA [Make American Great Again–Trump’s campaign slogan].

“Strap in fellas.”

Asked about the meeting, Caputo said, “We spent the afternoon at the Breitbart Embassy strategizing with Steven and his team, outlining how we will work together on this race.”

Asked if Bannon offered his support to Grimm, Caputo said, “Everything is on the table.”

Caputo, a former Trump campaign aide, is a pal of Bannon’s.

The Grimm meeting comes just a week after GOP insurgent Roy Moore defeated GOP establishment candidate Luther Strange in a primary race for an Alabama Senate seat.

Bannon — and his right-leaning media outlet Breitbart News — backed Moore. Strange lost despite the backing of President Trump and Senate Majority Leader Mitch McConnell.

Bannon, through a spokesman, had no immediate comment on whether he intends to side with Grimm in what is expected to be a nasty primary race in 2018.

Grimm’s run comes just 17 months after he was released from prison, where he was sentenced for concealing almost $1 million in receipts from a restaurant he co-owned in Manhattan.

As part of a plea deal, Grimm admitted to employing people ineligible to work in the United States and lying in a 2013 deposition.

Grimm, a former FBI agent and Marine, was re-elected in 2014 while under indictment. But just weeks later he pled guilty to tax fraud and vacated the seat — with Donovan wining the race to succeed him.

Donovan, the former Staten Island district attorney, said he’s ready to compare his government record to Grimm’s criminal record.

“I think the people of Staten Island and South Brooklyn will recognize the record of service that I have, being chief of staff of the borough president for 6 years, deputy borough president for 2 years, district attorney for 12 years – making Staten Island the safest community in the safest big city in America – and the success that we’ve had in the short period of time we’ve been in Congress,” Donovan told The Post.

“I think I’ll compare my record to whatever ‘record’ Michael Grimm might have.” Donovan said, making sure to say “record “in quotes.

Asked if it’s ironic race that he’s facing off against a convicted felon , Donovan said, “I think you’ll have to ask the voters if they find that ironic.”
