WASHINGTON (AP) — One year ago, President Barack Obama was barreling toward airstrikes in Syria when he abruptly announced that he first wanted approval from congressional lawmakers.

The move threw his policy into confusion and the strikes were eventually scrapped.

Now, as Obama again contemplates military action in Syria, the White House is suggesting it may not be necessary to get a sign-off from Congress.

While cautioning that Obama has made no final decisions, officials say there is a difference between last year's effort to strike Syria's government in retaliation for chemical weapons use and a bombing campaign against Islamic State militants that is now under consideration.

With some notable exceptions, there has been little clamor among congressional leaders for Obama to seek approval from Capitol Hill before proceeding with military action.
