Conservative Democrat Kyrsten Sinema of Arizona has infuriated voters across the country with her refusal to end or reform the Senate filibuster and, most recently, her devotion to Big Pharma donors that's jeopardizing the ability of Medicare to negotiate prescription drug prices—a key part of Biden's infrastructure package.

Sinema's vote for the infrastructure bill is vital for Democrats to pass the Build Back Better agenda in the Senate through reconciliation in an evenly divided Senate.

It was that frustration that led five veterans to announce their resignation from Sinema's advisory council in a scathing letter decrying her as an obstacle to progress.

The letter, obtained by the New York Times, reads in part:

"You have become one of the principal obstacles to progress, answering to big donors rather than your own people. ... We shouldn't have to buy representation from you, and your failure to stand by your people and see their urgent needs is alarming."

The letter marks the latest development in a whirlwind of criticism and outcry Sinema—and fellow conservative Democrat Senator Joe Manchin of West Virginia—are facing for their bulwark against progress on even the most popular Democratic stances. Their inaction on the filibuster and voting rights represents a threat to Democratic enthusiasm in the 2022 midterms.

People shared the rage of the veterans who quit Sinema's council.

They surmised Sinema is only in it for the money.

Sinema's seat is safe until at least 2025.
