WASHINGTON (Reuters) - U.S. lawmakers have few options for tamping down any escalation by President Donald Trump of tensions with Iran, despite Democrats' outrage over his failure to inform Congress in advance about a strike against a top Iranian military commander.
Members of Congress begin to return from their year-end holiday recess on Monday, and Democrats said they will attempt quickly to pass legislation to bar Trump - or any future U.S. commander-in-chief - from conducting a campaign against Iran without obtaining Congress' approval.
