Republican Donald Trump says the FBI's decision not to recommend criminal charges against Hillary Clinton is the greatest example yet that the system is "rigged."
Trump says Clinton put the "entire country in danger" and insists she was likely hacked.
"Her judgment is horrible," Trump says, adding, "She will be such a lousy president, folks."
Trump also had harsh words for President Barack Obama, arguing he should be at the White House working to defeat Islamic State militants and dealing with other issues instead of joining Clinton on the campaign trail.
He says Obama seems to be having too much fun, adding, "it's like a carnival act."
Sen. Bob Corker joined Donald Trump onstage at a rally in Raleigh Tuesday amid speculation about the Republican candidate's vice presidential deliberations.
Trump introduced the Tennessee senator and chairman of the Senate Foreign Relations Committee as "somebody respected by everybody."
Corker said he'd had a "pretty remarkable day" with Trump, spending time with his grown children and watching how he treats the people who work for him.
He told the enthusiastic crowd packed into Raleigh's Duke Energy Center for the Performing Arts that "the reason that you love him so much is because he loves you."
The pair hugged before Corker left the stage.
Trump's event comes several hours after Democratic rival Hillary Clinton held her first joint rally with President Barack Obama in North Carolina.
