The United States cares more about getting a good agreement than quickly concluding the renegotiation of the North American Free Trade Agreement, the US Treasury secretary said Sunday, reports AFP from Washington.

An informal deadline came and went this week for reaching an agreement in time for the Republican-controlled Congress to approve it before the November 6 midterm elections.

House Speaker Paul Ryan said Friday there was still "wiggle room" in the legislative calendar, giving negotiators a couple more weeks.
