From Politico:

Conservative filmmaker and activist James O’Keefe won’t be in Tampa, but the show he was  supposed to headline will go on.

O’Keefe will still speak via Skype on “the role of the citizen journalist” and take audience questions at Tuesday’s luncheon sponsored by the James Madison  Institute, a Florida-based nonprofit organization, the institute’s  communications director Tanja Clendinen said.

Clendinen said O’Keefe was not granted permission by the government to travel  to Tampa.

“He is currently on probation from some of his Louisiana investigation  activities, and his travel permission was revoked,” she said.
