New Jersey Gov. Chris Christie (R) will address the media Thursday morning following revelations that a staff member and two appointees orchestrated a traffic jam in Fort Lee, N.J., as apparent political retribution against the town's mayor.

The 11 a.m. news conference will take place in the governor's office in Trenton and will be live-streamed on Post TV.

Emails made public on Wednesday implicate Christie's chief of staff and two of his political appointees at the Port Authority in the closing of some lanes of the George Washington Bridge. The scandal raises doubts about efforts by Christie, considered a top GOP White House hopeful in 2016, to portray himself as above the political fray.

The controversy is the subject of a hearing scheduled for Thursday. And meanwhile, a Democratic state legislator is calling for a federal investigation into the lane closures, which according to a local EMS official delayed emergency response calls. A 91-year-old woman whose emergency call was delayed later died, according to the Bergen Record.

Christie did not speak to reporters Wednesday, canceling a morning appearance and issuing only a brief statement late in the afternoon. In the statement, Christie denied any knowledge of the scheme, saying he only learned about it Wednesday and that his staff had misled him about the situation.
