Joined by some surviving family members of September 11th first responders, President Donald Trump on Monday signed a bill fully funding the Victim Compensation Fund for all future health care needs.

"This law makes permanent the financial support for families who lost precious loved ones as the result of September 11th attacks," Trumps said at the signing.

The U.S. House passed the permanent funding stream earlier this month, putting pressure on the Senate to follow suit. The bill finally passed the Senate last week, 97-2, even though there was opposition from members of Trump's own Republican Party.

But when it came time to sign the bill, Trump declined to invite some of its key sponsors and biggest boosters, like New York Rep. Carolyn Maloney.

"I did not receive an invitation," Maloney said. "But it's not about me or anyone else; it's about America. It's a great win for America, for the American people, American values."

Trump also announced that he spent time at the World Trade Center site following the 9/11 attacks. It was a claim that was widely challenged on social media.

"Many of those affected were firefighters, police officers, and other first responders. And I was down there also. But I'm not considering myself a first responder. But I was down there. I spent a lot of time down there with you," Trump said.

Supporters say they are just happy to see the funding made permanent.

"Like we help our veterans, we had an obligation to help these people," Senate Minority Leader Charles Schumer said. "So now thank God they are getting the assistance they need."

The bill injects an immediate infusion of cash — $10 billion — which will mean benefits will no longer be at risk of being cut for those who most need them.

The fund's reauthorization has been a constant struggle over the nearly 20 years since the attacks. Those who have advocated for it were both relieved and frustrated that they were forced to make the case year after year.
