Vice President Joe Biden returned to Houston Tuesday afternoon to speak to delegates attending the 95th annual American Legion Convention.

Last week, the vice president was in Houston while he son, Delaware Attorney General Beau Biden, underwent testing at the MD Anderson Cancer Center.

Biden spoke about Syria during his remarks as the United States considers a potential military strike against that torn country.

"There is no doubt that an essential international norm has been violated," Biden said at the American Legion National Convention. "No one doubts that innocent men women and children have been the victims of chemical weapons attacks in Syria and there is no doubt who is responsible for this heinous use of chemical weapons in Syria: the Syrian regime."

Biden said Tuesday that he and Obama "believe that those who use chemical weapons against defenseless men women and children should and must be held accountable.

An estimated 10,000 delegates are registered to attend the convention, which is being held downtown at the George R. Brown Convention Center.

The delegates represent veterans of World War II, the Vietnam War and the Gulf War.

Members of the Sons of the American Legion and The Auxiliary are also meeting.

"The American Legion was chartered and incorporated by Congress in 1919 as a patriotic veterans organization devoted to mutual helpfulness,” according to its website. “It is the nation’s largest wartime veterans service organization, committed to mentoring youth and sponsorship of wholesome programs in our communities, advocating patriotism and honor, promoting strong national security, and continued devotion to our fellow service members and veterans."

The convention runs through Thursday.
