Barack Obama, in Georgia, calls Herschel Walker a ‘celebrity who wants to be a politician’

Former President Barack Obama repeatedly took aim at Herschel Walker, the Republican Senate nominee in Georgia who’s challenging Democratic Sen. Raphael Warnock in a crucial battleground state Senate showdown.

The former president, making his return to the campaign trail on behalf of fellow Democrats with just a week and a half to go until Election Day, criticized Walker, the former college and professional football star and first-time candidate, as "a celebrity to who wants to be a politician."

Obama, who remains the most popular person in the Democratic Party nearly six years after he left the White House, is trying to perform some last-minute political magic as Democrats desperately try to hold onto their razor-thin congressional majorities in the midterm elections. The former president is headlining rallies in five states holding key Senate and gubernatorial races.
