House Republicans reversed course Tuesday evening and moved toward the likely passage of the bipartisan agreement struck in the Senate to avoid the worst effects of the “fiscal cliff’’, setting up a late night vote to complete a wild day in which the critical legislation appeared to be on its political deathbed for several hours.

In a second huddle Tuesday, House Speaker John A. Boehner (R-Ohio) and Majority Leader Eric I. Cantor (R-Va.) outlined the options for handling the Senate plan while explaining the high "risk" involved with approving a different bill that might die in the other chamber, according to lawmakers exiting the evening meeting.
