Arizona Democratic Senator Kyrsten Sinema is scheduled to hold a fundraiser today with five business lobbying groups that oppose a massive spending bill containing some of the Biden administration’s top legislative priorities. That’s according to The New York Times, which reports attendees are being asked to write checks for up to $5,800 to Senator Sinema’s campaign. Sinema says she opposes the spending bill’s price tag of $3.5 trillion over 10 years. The legislation would increase taxes on wealthy individuals and corporations in order to expand the social safety net, improve worker rights and combat the climate crisis. Sinema’s support is critical to Democrats’ plans to use a budget reconciliation bill to pass the legislation in the evenly divided Senate.
