The Biden administration has “knowingly and unlawfully” provided more than $1.5 billion in aid to Gaza and the West Bank, allowing US tax dollars to “subsidize” Palestinian terror groups like Hamas, according to a lawsuit brought by Rep. Ronny Jackson and victims of past terror attacks in Israel.

President Biden and Secretary of State Antony Blinken have “known for years” that the US aid is providing “material support” for Hamas’ “tunnels, rockets, weapon procurement, and command and control infrastructure,” among other terror structures, an amended complaint filed March 25 states.

But since taking office, Biden and his officials have still pushed for the funding to the UN Relief and Works Agency (UNRWA) and other groups in the West Bank and Gaza — despite internal warnings about the “high risk” of the cash falling into the hands of terror groups in direct violation of the Taylor Force Act, signed into law in 2018 by President Donald Trump.

The aid for meant social services, education and infrastructure allowed the Palestinian Authority — which is barred by the Taylor Force Act from receiving US funding — to funnel its own assets to terrorism, the complaint argues.

The complaint, first filed last year by the conservative group America First Legal, was amended to include new emails obtained through Freedom of Information Act (FOIA) requests that also reveal the administration’s attempts to undermine Israel.

“It’s pretty clear that they came in with an intent and a policy to overturn what the Trump [administration] had done with respect to Israeli sovereignty over Jerusalem,” Reed Rubinstein, a lawyer for America First and a former US Deputy Associate Attorney General during the Trump administration, told The Post Monday.

“They knew that by increasing the money, we were going to see increased terror attacks. … And they did it anyway,” he said. “These folks came in with an absolute agenda to empower the Palestinians [and] flood money into Gaza and the West Bank.”

One March 1, 2021, email cited in the filing was sent by Hady Amr, the special representative for Palestinian Affairs, to George Noll, the chief of the US Office of Palestinian Affairs, and discusses the “progress” they had been making ahead of Israel’s parliamentary elections later that month

“Got the memo on elections,” Amr told Noll, in a heavily redacted message. “We are making progress. This is great.”

Another exchange, on May 24, 2021, following Hamas’ 11-day conflict with Israel, discusses “humanitarian response and reconstruction” efforts in the Gaza Strip, which Rubinstein said would have provided cement and other materials that could have been “diverted” to the terror group’s more than 350-mile-long tunnel system.

“The idea that they didn’t know that they were subsidizing these activities is fantasy,” Rubinstein added, saying that the complaint will dig up the extent to which US government funding was “subsidizing Hamas’ tunnels” soon after the May 2021 fighting.

“You can see from these emails, it gives you a real sense of where senior decision-makers were at … the policy tools of the US government [and] how they should be used,” he said. “I don’t know how you get anything other than then a sense that there was very deep hostility to the Jewish state.”

The Biden administration moved to dismiss the case last year, but a federal judge denied the motion on Oct. 9, two days after Hamas terrorists rampaged across southern Israel, killing an estimated 1,200 people — including 33 Americans.

The suit is meant to stop any further funding of Palestinian terror operations that lead to killings, such as the 2016 stabbing of Taylor Force, a US Army veteran of the Iraq and Afghanistan wars, in Tel Aviv — and the near-death of New Jersey native Sarri Singer in a 2003 suicide bombing attack in Jerusalem.

The Biden administration contributed more than $1 billion to the Palestinian refugee organization UNRWA before cutting off the money following reports that its employees participated in the Oct. 7 terror attack.

A March 2021 waiver that the State Department obtained from the US Treasury had admitted that American aid funding was at “high risk” of being obtained by Hamas, as well as other terror groups like Palestinian Islamic Jihad, the Washington Free Beacon first reported.

That waiver is included in the lawsuit’s exhibits, along with a State Department Office of Inspector General report in November 2023 that also confirmed the same “high risk” of aid funding being diverted to terrorism.

The Palestinian Authority is also slated to contribute at least $97 million to more than 13,000 Hamas terrorists that participated in the Oct. 7 attacks, according to a Free Beacon report also cited in last month’s filing.

“We are currently witnessing the devastating effects of the Biden administration knowingly breaking the Taylor Force Act, which President Trump signed into law,” Jackson (R-Texas) told The Post. “There is no doubt that the world is less safe now under the failed leadership of Biden and Secretary Blinken compared to four years ago under President Trump.

“Biden and Blinken have blood on their hands, and sending millions of fungible American taxpayer dollars to UNRWA has directly led to Palestinian terror against Israel. The Middle East is getting less stable by the minute due to the foolishness and weakness of the Biden administration, and I will not stand by while things continue to deteriorate!”

Rubinstein said the plaintiffs, who filed their complaint in US District Court for the Northern District of Texas, are expecting a response from the government next month.

“As a general matter, we do not comment on ongoing or pending litigation,” a State Department spokesperson told The Post.
