What is a recommit?
A motion to recommit returns a bill to committee, in effect killing it. However, a motion to recommit with instructions is a last opportunity to amend the bill.
The instructions to the committee direct changes to the text of the bill. If adopted, the chairman of the named committee immediately stands and reports the change back to the House. The next step is the House vote on final passage of the bill.
Minority Members receive priority of recognition for offering motions to recommit. --C-Span Congressional Glossary
