Senator Kirsten Gillibrand put President Barack Obama on the spot at a meeting with Democratic senators Wednesday, asking if he would commit to working with Congress to pass a fully funded and comprehensive 9/11 health bill.

The president says he is committed to working with lawmakers, but didn't promise to completely back the legislation, which would spend about $11 billion over 30 years to care for the growing number of people getting sick.

During an appearance Wednesday on NY1's "Inside City Hall," Gillibrand urged her colleagues to make sure health care for first responders is a top priority.

"Some people have even died, some people are incapacitated, some people are gravely disabled, so we need to do everything we can to protect them and make sure their health care is covered," said Gillibrand.

A group of September 11th responders and widows gathered earlier in the day at the World Trade Center site to call on President Obama to fully support the bill, which would provide guaranteed money for research and care moving forward. Currently, such funds are allocated in Washington on an annual basis.

"On his campaign trail, he said he would sign this bill if it made it to his desk. He said it. It's on record. In November he said he supports us. What has changed since now and November? I can tell you the only thing that hasn't changed is people are still dying," said September 11th first responder John Feal.

Last week, Health and Human Services Secretary Kathleen Sebelius said the Obama administration does not support mandatory funding for the permanent treatment plan.
