Conservative House lawmakers said Thursday that they achieved “a huge win” in a deal to postpone a floor vote to impeach IRS Commissioner John Koskinen.

Judiciary Committee Chairman Bob Goodlatte, R-Va., and leaders of the House Freedom Caucus worked out a last-minute deal Wednesday to postpone the impeachment vote, which Rep. John Fleming, R-La., had called up on Tuesday. Instead of the vote, the Judiciary panel will hold an impeachment hearing Wednesday where Koskinen will be questioned under oath.
