An online fundraiser for fired FBI Deputy Director Andrew McCabe’s defense fund will stop taking donations at 7 p.m. Monday after it more than tripled the original $150,000 goal.

The GoFundMe campaign had raised $546,375 as of 2:30 p.m. — even after the initial goal was upped to $250,000.

“The outpouring of support on GoFundMe has been simply overwhelming and has led to contributions that have left us stunned and extraordinarily grateful,” the ex-G-man said in a message posted on the site.

“I never imagined that I would need to rely on this type of assistance. The fact is that if I am going to continue taking a stand against the unfair way I have been treated, I will need the help of a talented and courageous team behind me.”

Attorney General Jeff Sessions canned McCabe, a 21-year FBI veteran, on March 16 — two days before he would have been able to collect his full federal pension.

McCabe had stepped down from his post in January, but was still on the payroll, using accumulated time until he became eligible for his pension.

In the months before McCabe was given the boot, President Trump repeatedly attacked him on Twitter.

“How can FBI Deputy Director Andrew McCabe, the man in charge, along with leakin’ James Comey, of the Phony Hillary Clinton investigation (including her 33,000 illegally deleted emails) be given $700,000 for wife’s campaign by Clinton Puppets during investigation?” he tweeted, referring to a campaign donation to McCabe’s wife when she was running for a seat in the Virginia legislature from a PAC operated by a Clinton ally.

He went after him again on March 18 after it was revealed that McCabe had kept contemporaneous notes on his interactions with the president.

“Spent very little time with Andrew McCabe, but he never took notes when he was with me. I don’t believe he made memos except to help his own agenda, probably at a later date. Same with lying James Comey. Can we call them Fake Memos?” the commander-in-chief tweeted.

And he gloated about the firing just hours after McCabe was let go.

“Andrew McCabe FIRED, a great day for the hard working men and women of the FBI – A great day for Democracy. Sanctimonious James Comey was his boss and made McCabe look like a choirboy. He knew all about the lies and corruption going on at the highest levels of the FBI!” Trump wrote.

McCabe said in the GoFundMe statement he was determined to pursue the truth as he fights Sessions’ accusations that he had misled investigators looking at his behavior in the Clinton probe.

“Hopefully our efforts, fueled by your incredible support, will encourage others to stand up for themselves, and the truth, as well. It is not lost on me that each contribution reflects not just someone’s well wishes, but also their acknowledgment that something in this situation is not fair or just,” he said.

More than 13,000 people donated during the four days the page was active.
