NFL legend Herschel Walker is following in his buddy Donald Trump's footsteps and starting his own political career ... by running for U.S. Senate in the state of Georgia.
Walker officially filed paperwork for the seat -- currently held by Democratic U.S Sen. Raphael Warnock -- with the Federal Elections Commission on Tuesday ... and is surely expected to get public support from #45.
Of course, Trump and Walker have been tight for decades ... dating back to when the running back played for the USFL's New Jersey Generals, which the businessman owned at the time.
