Sen. Debbie Stabenow (D-Mich.) on Monday signed a letter urging Majority Leader Harry Reid (D-Nev.) to pass a public health insurance option using the budget reconciliation process.

So far, 22 senators have signed the letter sponsored by the Progressive Change Campaign Committee (PCCC). Stabenow is a liberal member of the powerful Senate Finance Committee.

The PCCC's Adam Green announced Stabenow's support on MSNBC Monday evening. 

Stabenow's signature underscores growing momentum behind reintroducing the government-run plan, which Reid stripped from the bill in December after he could not attract enough centrists to support the bill with it included.

Using the reconciliation process, however, would allow senators to pass it with only 51 votes.

The White House did not include the public option in its healthcare plan released Monday morning but said it was up to Reid whether or not to include it. 

Reid has signaled openness to reintroducing the public option but has not yet made a definitive statement.

Two Senate Democratic leaders have signed the letter; Senate Democratic Caucus Vice Chairman Charles Schumer (D-N.Y.) and Democratic Senatorial Campaign Committee Chairman Robert Menendez (D-N.J.)

More than 100 House lawmakers have signed a similar letter.

Republicans have spoken out against the renewed support for the public option, saying it would thwart the will of voters who have voiced opposition towards Democratic policies.
