New Jersey Gov. Chris Christie and Cranston Mayor Allan Fung are both at the center of controversies that could affect their political futures.
Christie would like to advance from governor to president. It won't happen if he is tied to the closing of three lanes on the George Washington Bridge.
"If there's any hint that he actually knew or if he looked the other way kind of knowing his staff members were doing this, he is history," said Darrell West of the Brookings Institution during a taping of "10 News Conference" on Friday.
Fung would like to be governor of Rhode Island.
He has a problem with his police department issuing a flurry of tickets in the districts of two City Council members who voted against a new police contract.
Fung stepped up his response Thursday, calling for a state police investigation. And Friday, he placed the police chief on paid administrative leave.
Christie, after months of criticism, also met with the press Thursday. In Christie's case, there is now an outside investigation that will involve many more documents and communications, and possibly reveal more than just this one incident, which presents different problems.
"What does this tell us about the Christie administration? What does it tell us about his character, his mentality, how he approaches issues? He could have points of vulnerability on a lot of other issues," West said.
The good news for Fung is that he doesn't have a legislative body issuing subpoenas for documents, and nobody has accused him of telling police to issue the offending tickets.
