WATCH: Barack Obama Talks Same-Sex Marriage On 'The View'

President Barack Obama has been making the talk show rounds lately in preparation for his upcoming presidential race against inevitable Republican ticket nominee Mitt Romney, and his latest stop on the talk show circuit will be on today's episode of ABC's The View, which will be attended by all The View hosts, Barbara Walters, Joy Behar, Whoopi Goldberg, Sherri Shepherd, Elisabeth Hasselbeck.

Last week Obama made "that historic decision to say that [he was] in favor of gay marriage," Walters points out on Tuesday's interview with Obama on The View. Walters also pointed out that the idea might be unpopular for some. "There are 30 states which are not," Walters said, and "also federal laws that impinge on the rights of gays." Walters asked how far Obama was willing to go to stand behind his statement and his support of same-sex marriage.

"My justice department has said to the courts, we don't think the Defense of Marriage Act is constitutional," Obama said, referring to the federal law that defines marriage as a legal union between a man and a woman, specifically. "This is something that historically had been determined at the state level and part of my believing ultimately that civil unions weren't sufficient."

When Walters asked if he would fight to repeal the Defense of Marriage Act, Obama was less direct. "Congress is clearly on notice that I think it's a bad idea."

Today's episode, airing at 11 a.m. EST on ABC, will mark Obama's fourth appearance on The View since he took office in 2009.
