A bill enhancing health care and disability benefits for millions of veterans exposed to toxic burn pits won final approval in the Senate on Tuesday, ending a brief stalemate over the measure that had infuriated advocates and inspired some to camp outside the Capitol.

The Senate approved the bill by a vote of 86-11. It now goes to President Joe Biden’s desk to be signed into law. He has said the bill “makes good on our sacred obligation” to care for veterans and their families.

The Senate had overwhelming approved the legislation back in June, but a do-over was required to make a technical fix. That process derailed when Republicans made a late attempt to change another aspect of the bill last week and blocked it from advancing.

The abrupt delay outraged veterans groups and advocates, including comedian Jon Stewart. It also placed GOP senators in the uncomfortable position of delaying the top legislative priority of service organizations this session of Congress.

A group of veterans and their families have been camping out at the Capitol since that vote. They had endured thunderstorms and Washington’s notorious August humidity, but they were in the galleries as senators cast their votes.

“You can go home knowing the good and great thing you have done and accomplished for the United States of America,” Senate Majority Leader Chuck Schumer told them.

The legislation expands access to health care through the Department of Veterans Affairs for millions who served near burn pits. It directs the VA to presume that certain respiratory illnesses and cancers were related to burn pit exposure, allowing veterans to obtain disability payments to compensate for their injury without having to prove the illness was a result of their service.

Roughly 70% of disability claims related to burn pit exposure are denied by the VA due to lack of evidence, scientific data and information from the Defense Department.

The military used burn pits to dispose of such things as chemicals, cans, tires, plastics and medical and human waste.

Hundreds of thousands of Vietnam War era veterans and survivors also stand to benefit from the legislation. The bill adds hypertension, or high blood pressure, as a presumptive disease associated with Agent Orange exposure.

The Congressional Budget Office projected that about 600,000 of 1.6 million living Vietnam vets would be eligible for increased compensation, though only about half would have severe enough diagnoses to warrant more compensation.

Also, veterans who served in Thailand, Cambodia, Laos, Guam, American Samoa and Johnston Atoll will be presumed to have been exposed to Agent Orange. That’s another 50,000 veterans and survivors of deceased veterans who would get compensation for illnesses presumed to have been caused by their exposure to the herbicide, the CBO projected.

The bill is projected to increase federal deficits by about $277 billion over 10 years.
