WASHINGTON (AP) — President Barack Obama's national security team scheduled briefings Saturday for senators about Syria as the White House readied for a possible military strike.

Vice President Joe Biden was at the White House, according to his office, while Defense Secretary Chuck Hagel and other military officials were also convening there.

In the afternoon, senior officials planned to consult by phone with Senate Democrats and Republicans. The calls will be unclassified, meaning officials will be limited in what they can say.

Secretary of State John Kerry, Director of National Intelligence James Clapper and Obama's national security adviser, Susan Rice, also were to participate.

The briefing was coming a day after the administration released an intelligence report concluding that Syrian President Bashar Assad's government killed more than 1,400 last week in a chemical attack.

Obama says the U.S. is considering a limited strike in response.
