Bradley Cooper visited the White House on Monday for a discussion about negative attitudes toward mental illness. Actress Glenn Close, who founded Bring Change 2 Mind partly in reaction to her sister's bipolar diagnosis, was also a panelist.

President Obama said in his remarks that the conversation about mental illness, experienced by one in five adults, needs to be elevated to the national level. Cooper, whose "Silver Linings Playbook" character had bipolar disorder, visited D.C. in January to advocate the same goal of removing the stigma of mental illness.

Washingtonians also spotted Cooper visiting his college stomping ground at the Tombs in Georgetown on Sunday night.
