Senate Minority Leader Chuck Schumer and other Senate Democrats are pressing the Trump administration to announce its decision on whether to add several diseases to the list of conditions that automatically qualify for veterans benefits because they are linked to Agent Orange.

Schumer took to Twitter Wednesday urging the White House to act, following a failed attempt earlier in the day by Sen. Sherrod Brown, D-Ohio, to introduce a resolution encouraging President Donald Trump to expand the list of health conditions related to Agent Orange to include bladder cancer, Parkinson’s like symptoms, hypothyroidism and hypertension.

The resolution was blocked by Senate Veterans Affairs Committee Chairman Sen. Johnny Isakson, R-Ga., who said the decision must not be made until the science can justify spending taxpayer dollars.

“It’s time to make sure every that every benefit we promise the veteran we have the money to do it.” Isakson said.

Last month, internal documents obtained by Military Times from a veteran showed that two years ago, VA Secretary Dr. David Shulkin agreed to add three of the health conditions — bladder cancer, Parkinson’s like symptoms, hypothyroidism — to the list but White House officials, including Office of Management and Budget Director Mick Mulvaney, challenged his authority and blocked the announcement.

The report of the interference riled lawmakers who have worked for years to help affected constituents.

In introducing his resolution, Brown said “time is running out” for 83,000 veterans who are sick and waiting for an announcement of the decision, which was promised by VA officials earlier this year.

"Some might accuse this body that we are waiting for them to die, as hard as it is to say that,” Brown said on the Senate floor. "Veterans shouldn’t have to fight this one at a time … we did this to them. The American government decided to spray Agent Orange. We knew it was harmful.”
