The House won't vote this week on an extension to the Affordable Care Act's enhanced premium subsidies, which lapse at the end of the year. An 11th-hour effort by moderate Republicans to put an extension on the floor for a vote failed Tuesday night, when the House Rules Committee blocked several of the amendments they were seeking to the attach to a GOP health care plan released last week. The GOP plan does not include an extension. The committee advanced the bill to the floor late Tuesday. A vote is expected Wednesday.
