President Barack Obama says he is "still working" on his views of gay marriage.

Obama's comments come one year after he told liberal bloggers that his views on gay marriage were "evolving." He supports civil unions, but has thus far not backed same-sex marriage.

During an interview with ABC News on Monday, Obama said gay couples should, at a minimum, have strong civil unions. But he stopped short of backing gay marriage.

Obama says his evolving views are influenced by friends, family and children of gay couples he knows who are thriving.

Numerous recent polls suggest a slight majority of Americans favor giving same-sex couples the right to marry.
