A GOP lawmaker took to Twitter on Friday to urge supporters to pressure lawmakers to vote against the healthcare bill in the wake of reports that Democrats have having trouble marshaling votes. 

Rules Committee member Rep. Virginia Foxx (R-N.C.) cited comments from House Majority Leader Steny Hoyer's (D-Md.) that Democrats do not have the 218 votes necessary to pass healthcare reform. 

Foxx tweeted before a 2 p.m. Rules Committee meeting designed to establish the terms of debate for the healthcare vote scheduled to be held at 6 p.m. tomorrow. She seemed encouraged that Republicans could delay the vote even further:

Rules Comm meets at 2 pm for tax increase bill called health care. Will meet all night. Democrats do not have votes. Tell them no

Hoyer said that "delay tactics" could prevent the 6 p.m. vote from occurring on time tomorrow. Republicans have complained that the inclusion of an abortion compromise into the bill at today's Rules Committee hearing violates Hoyer House Speaker Nancy Pelosi's (D-Calif.) pledge to post the full text of legislation online 72 hour before a vote.

But Republicans say that divisions in the Democratic caucus are causing the delays.

Foxx gained the ire of liberals when she said on the House floor this week that Democratic healthcare reform proposals pose a larger threat to America than terrorism.
