The war of words between President Obama and Democratic Sen. Elizabeth Warren escalated Monday, with the White House accusing the progressive lawmaker of leveling "false criticism" against its trade push.

After Obama over the weekend accused Warren of distorting legislation that would grant him so-called Fast Track authority, the senator on Monday called on him to make the bill public.

The White House countered that Warren already has the ability to read the bill in its current form, saying the administration has set up a private viewing room on Capitol Hill for lawmakers.

"There is no need for this false criticism that the members of Congress aren't aware of what is being negotiated," said White House press secretary Josh Earnest.

"If they're not aware of what is being negotiated, it's because they have failed to take the responsibility to read the document."

The White House is trying to tame a revolt from the Left on legislation that would ease Obama's efforts to finalize the Trans-Pacific Partnership, a 12-nation pact. Trade Promote Authority would allow the deal to go through Congress without amendments.

Progressives argue that TPP would harm American workers by essentially outsourcing jobs. In a rare sign of bipartisanship between the White House and Republicans, Obama and most conservative lawmakers say the deal would open up untapped markets and grow U.S. exports.

Warren has also argued that Fast Track authority could undo banking reforms, a claim the White House has also dismissed as false.
