WASHINGTON (AP) — Confronted with a revolt among the rank and file, House Republicans abruptly scrapped a vote Thursday night on legislation allowing tax rates to rise for households earning $1 million and up, complicating attempts to avoid a year-end “fiscal cliff” that threatens to send the economy into recession.

The legislation “did not have sufficient support from our members to pass,” Speaker John Boehner conceded in a brief statement. At the same time he challenged President Barack Obama and Senate Majority Leader Harry Reid, D-Nev., to work on legislation to avoid across-the-board tax increases and deep spending cuts due to take effect in less than two weeks.
