Sen. Kyrsten Sinema signed off on sweeping Democratic legislation Thursday that would provide new spending to mitigate climate change and extend health care access while taxing corporations.

The Arizona Democrat's announcement likely unlocks the votes needed to pass the bill in the Senate.

Sinema said her support came after Democratic leaders agreed to remove a provision on closing the so-called carried interest tax loophole that enables wealthy hedge fund and investment managers to pay lower taxes.

“We have agreed to remove the carried interest tax provision, protect advanced manufacturing, and boost our clean energy economy in the Senate’s budget reconciliation legislation," she said in a statement Thursday. "Subject to the Parliamentarian’s review, I’ll move forward."

Her comments on the bill, known as the Inflation Reduction Act, came after a weeklong silence that left many Democrats nervous that the enigmatic centrist may not sign off on it. Democrats have no hope of winning any Republican support, meaning all 50 senators in the caucus are needed to pass the measure.
