House Republican leaders announced Wednesday morning that they would take a risky double-barreled attack on President Obama's health-care law, making it the cornerstone fight over government funding due to expire Sept. 30 and the effort to lift the Treasury's borrowing authority.

Speaker John A. Boehner (R-Ohio), flanked by his leadership team, told reporters that the stopgap government funding bill that they will advance Friday would yield to conservative demands of including a rider to block funding for the law commonly known as Obamacare.

"The law is a train wreck," Boehner said. "The president has protected American big business. It's time to protect American families from this unworkable law."
