Rep. Carolyn Maloney, the lead co-sponsor of the 9/11 Victims Fund, was snubbed by the White House on Monday, when President Trump signed the bill into law during a Rose Garden ceremony, her office said.

A White House official told the print pool reporter that all members of Congress had been invited, but the New York Democrat's office said to CBS News in a statement that Maloney "did not receive an invite to today's bill signing nor did a staff member receive one on her behalf." The legislation provides financial aid to first responders and survivors of the Sept. 11, 2001 attacks to help them pay their health care bills.

Maloney was a vocal supporter of the bill long before it attracted national attention. She had been wearing a FDNY firefighter's jacket since February and vowed to never take it off until her colleagues passed legislation that would fully compensate the victims of the 9/11 attack and their families. She even wore the heavy coat at this year's Met Gala dinner in New York City.

At the time, she reportedly said, "I do not intend to take it off until we pass this bill."

On Monday, Mr. Trump, surrounded by dozens of first responders and their families directly impacted by the legislation, did not recognize any Democrats who were crucial to securing support for the bill beyond Maloney's efforts — including New York Sens. Chuck Schumer and Kirsten Gillibrand.

However, the president did single out Reps. Chris Collins, Mark Meadows and Deb Fischer, among other Republicans, for thanks.

With Mr. Trump's signature, the reauthorization allows 9/11 victims and their families to file claims for necessary medical funds through 2090 but they will be paid out through 2092. The bill overwhelmingly passed in the Senate in a 97 to 2 vote last week.

"The true Twin Towers of New York are the FDNY and the NYPD, and fully funding and permanently authorizing the 9/11 Victim Compensation Fund is the least we can do to honor their sacrifices," Maloney said after the bill's passage.
