President Trump spiked the football Saturday over the firing of career G-man Andrew McCabe, bragging that bureaucrats’ misbehavior in the Russia probe and Hillary Clinton e-mail investigation is clear to all.

Americans finally realize that “there was tremendous leaking, lying and corruption at the highest levels of the FBI, Justice & State. #DrainTheSwamp,” the president claimed in a 1:11 p.m. tweet.

He also boasted about House Republicans’ decision to shut down their own investigation of allegations that his campaign colluded with Russia.

“As the House Intelligence Committee has concluded, there was no collusion between Russia and the Trump Campaign,” Trump crowed on Twitter.

But the former FBI deputy director — who was fired late Friday by Attorney General Jeff Sessions just two days before he was eligible to take a pension — may be plotting his own moves.

Word leaked that McCabe kept memos about all of his interactions with Trump — and that he has handed them over to special counsel Robert Mueller’s investigation of Trump’s campaign.

The memos are similar to those kept by former FBI Director James Comey, sources said. The notes led to Mueller’s appointment when Comey leaked them after his own firing in May.

In a second tweet Saturday, Trump said Comey’s and McCabe’s bias against him wrecked their reputations and that slanted mainstream news coverage won’t restore their good names.

“The Fake News is beside themselves that McCabe was caught, called out and fired,” he wrote. “How many hundreds of thousands of dollars was given to wife’s campaign by Crooked H friend, Terry M, who was also under investigation? How many lies? How many leaks? Comey knew it all, and much more!”

For those who need to check the scorecard on those players:

“Crooked H” refers to Hillary Clinton.

“Terry M” is Terry McAuliffe, a close Clinton ally and governor of Virginia from 2014 to 2018.

“Wife’s campaign” is the 2015 Virginia state Senate run of McCabe’s wife, Jill, who lost the race even though McAuliffe steered nearly $500,000 in contributions her way.

“He brought up my wife every time I ever spoke to him,” McCabe told CNN after his firing. Trump repeatedly called her a “loser” or a “problem,” McCabe said.

Sessions fired McCabe for allegedly lying to Department of Justice investigators and leaking to the news media.

FBI disciplinary officials recommended the sacking, Sessions said. A soon-to-be-released report from DOJ Inspector General Michael Horowitz is expected to criticize McCabe and others for their role in the Clinton e-mail probe.

McCabe resigned as FBI deputy director in January when word of the IG’s findings began to circulate — but he remained an FBI employee.

He had planned to take early retirement on his 50th birthday Sunday. By firing him two days before that, Sessions may cost him tens of thousands of dollars in pension payouts, experts say.

Meanwhile, Former Manhattan US Attorney Preet Bharara took a thinly veiled swipe at Attorney General Jeff Sessions in a caustic tweet.

“Once upon a time I thought Alberto Gonzales was the weakest and most craven Attorney General in modern times,” Bharara posted late Friday. “I was wrong.”

Gonzales, George W. Bush’s attorney general, was widely denounced for his sudden dismissal of seven US attorneys in 2006 for reasons that remain murky.

President Trump fired Bharara a year ago after requesting — and not receiving — a letter of resignation from him. Bharara has been a vocal Trump critic ever since.
