In explaining why Democrats have yet to repeal “Don't Ask, Don't Tell,” Vice President Joe Biden said “it's complicated.”

Appearing on CNN's Larry King Live, the 67-year-old Biden agreed that he opposes the law that bans gay and bisexual troops from serving openly but added that the issue is not easy.

“This is complicated for people to understand and I don't blame them,” Biden said.

“We are pushing as hard as we can,” he added. “We just had a meeting today with the leadership in the Congress saying we very much would like to see you pass legislation now saying end 'Don't Ask, Don't Tell.'”

When asked by King, “Think we'll see the end of it by the end of the year?” Biden responded: “I hope so.” (The video is embedded in the right panel of this page.)

The Senate's Democratic leadership has pledged to put repeal up for a vote after the Thanksgiving break, and several GOP senators have suggested they're leaning in favor of ending the policy.
