(CNN) -- Two employees at the Baltimore, Maryland, branch of the liberal community organizing group ACORN were caught on tape allegedly offering advice to a pair posing as a pimp and prostitute on setting up a prostitution ring and evading the IRS. The footage, which appears to have been edited in places, was recorded and posted online Thursday. The video footage -- which has been edited and goes to black in some areas -- was recorded and posted online Thursday by James O'Keefe, a conservative activist. He was joined on the video by another conservative, Hannah Giles, who posed as the prostitute in the filmmakers' undercover sting.
