Sinema says she will 'move forward' on economic bill, giving Democrats the votes to move ahead

Sen. Kyrsten Sinema on Thursday night agreed to support the Democrats' economic bill, giving Democrats the 50 votes they need to pass the legislation in the coming days.

Sinema's support is critical given that all 50 Republicans will oppose a plan they argue would hurt the economy and cost far more than Democrats are contending -- so any one Democratic defection could sink it.

In a statement, Sinema indicated that she won several changes to the tax provisions of the package, including removing the tax on carried interest, which would have impacted hedge fund managers and private equity. That proposal would have raised $14 billion.
