The Arizona Democratic Party on Saturday passed a resolution threatening a no-confidence vote against Sen. Kyrsten Sinema, D-Ariz., if she does not support the party’s agenda and the elimination of the filibuster.

Sinema has received at least $923,000 from industry groups and corporations leading the lobbying blitz to kill or defang the spending proposal, according to an analysis by the progressive government watchdog group Accountable.US.

“Super-rich corporations have given Sen. Sinema nearly a million reasons to vote against making them pay their fair share in taxes,” Kyle Herrig, president of Accountable.US, said in a statement. “Make no mistake, if she sides with her wealthy donors and kills popular investments to jump-start the economy, everyday families — including across Arizona — will pay the price.”
