WASHINGTON (AP) - Heat is building on divided Republicans, who are convening the House this weekend in hopes of preventing a government shutdown but remain under tea party pressure to use a must-do funding bill to derail all or part of President Barack Obama's health care law.

WASHINGTON (AP) Heat is building on divided Republicans, who are convening the House this weekend in hopes of preventing a government shutdown but remain under tea party pressure to use a must-do funding bill to derail all or part of President Barack Obama's health care law.

The weekend session comes after the Senate on Friday sent back to the House legislation to keep the government's doors open until Nov. 15, but only after Democrats stripped from the bill a provision to defund the new health care law.

Congress faces a midnight deadline on Monday. Failure to pass a short-term funding bill by then would mean the first partial government shutdown in almost 20 years.
