Actor Danny Glover, the star of Lethal Weapon, Witness, the Color Purple, and other Hollywood movies came to the Washington Post TV studio Monday to film an interview urging more Americans to get tested for HIV. The activist was in Washington to lend his celebrity to raise awareness for AIDS, which has claimed more than 30 million lives. Glover’s brother has HIV. The actor said his wish is that all people, especially the poor who often lack information about the disease, understand that medical treatment can halt the progression of the virus. Medicine can also prevent the spread of the virus to others. “Go get tested,” said Glover. Listen here to what else Glover, who has more than 1 million Twitter followers, had to say.
