WASHINGTON (AP) — Possible House action this week against Iran could fall short of new penalties that might derail a short-term nuclear agreement and Senate steps seem further off, legislatives aides said Wednesday, as the Obama administration appealed for patience.

In the House, the aides said Majority Leader Rep. Eric Cantor, R-Va., could introduce a nonbinding resolution as early as Thursday spelling out suggested terms for any final deal. The goal would be a vote before the House leaves on recess Friday.
