Michael Lohan tried to visit daughter Lindsay Lohan at the Betty Ford Center for “Family Week,” but was turned away, according to TMZ.

But he’s not giving up, he insists. “I am not giving up on anything,” Michael says. “I am certainly not giving up on Lindsay or my kids.”

Michael insists his ex-wife, Dina Lohan, is the one trying to keep him away from their daughter. “Until July 6 we were in contact constantly,” he says.
