One of the more liberal members of the House Democratic Caucus took to Twitter on Monday to push back at the Obama administration's efforts to back away from a public health insurance option.

Rep. Keith Ellison (D-Minn.) tweeted:
Time to defend Public Option in health care reform. HHS Sec. Sebelius, HHS, said PO was "not the essential element" of reform. Yes it is!

The Minnesota Democrat joined a chorus of liberal Democrats who criticized remarks made by Health and Human Services Secretary Kathleen SebeliusKathleen SebeliusFormer health chiefs: Stabilizing ObamaCare markets benefits Republicans OPINION | 5 big ideas to halt America's opioid epidemic Aligning clinical and community resources improves health MORE and White House Press Secretary Robert Gibbs that suggested that a public option is not the "essential element" of healthcare reform.

Rep. Anthony Weiner (D-N.Y.) said that "leaving private insurance companies the job of controlling the costs of healthcare is like making a pyromaniac the fire chief." Weiner also said the president could lose as many as 100 votes on the health bill if the public option is not included.

House Speaker Nancy Pelosi (D-Calif.) issued a statement backing the public option but did not specifically address the administration officials' comments.

Both Gibbs and Sebelius made their comments on Sunday talk shows this week.
