Jackson said Obama was "talking down to black people" and he threatened to cut off a certain part of the senator's anatomy. Fox News said Jackson made the comments while he was miked and awaiting a Fox & Friends interview from Chicago Sunday.
Jackson said he did not know his mike was live when he made the comments, before a Fox News interview, and he went on CNN to apologize to Obama for the remarks after the story got out.
The incident overshadowed another Obama-related story: his vote to support a FISA (Foreign Intelligence Surveillance Act) bill that included immunity for telecommunications companies that helped the government to tap into phone calls.
Obama initially opposed the bill and attempted to excise the phone-company protections from it, but he eventually voted for the larger bill, which passed Thursday.
