PEMBROKE PARK, Fla. -

Congressman Connie Mack IV discusses his run for the U.S. Senate seat his father once held for 12 years.

He also talks about that big endorsement he received this week from former Florida Gov. Jeb Bush.

Mack was already leading in the polls but will it be enough to give him a primary win.

Also we'll ask him about the harsh and downright nasty criticism coming from another challenger in the Senate race and former friend George LeMieux.
