The House will not vote this week on extending enhanced Affordable Care Act premium subsidies, which are set to expire at the end of the year.

An attempt by moderate Republicans to force a vote failed after the House Rules Committee blocked proposed amendments to a GOP health care bill that does not include an extension.

Moderates warn that letting the subsidies lapse could sharply raise insurance premiums for more than 20 million Americans and carry serious political consequences.

Speaker Mike Johnson said efforts were made to allow a vote but acknowledged no agreement was reached, despite some ideas still being discussed, CBS News has reported.

Democrats and some Republicans are now pushing discharge petitions to force a vote, but time constraints make action before the deadline unlikely.
