WASHINGTON (AP) - The White House is making a big push to rally members of Congress and the American public behind President Barack Obama's plan for a U.S. military strike against Syria.
His administration says the government of Syrian President Bassar Assad used chemical weapons in an attack last month near Damascus, and that a strong U.S. response is needed to deter the future use of deadly chemicals.
Syria claims rebels carried out the Aug. 21 attack.
Vice President Joe Biden plans to host a dinner tonight for a group of Senate Republicans. And lawmakers should expect more phone calls from top officials.
Obama is giving a national address Tuesday night.
