DENVER (AP) -- A man arrested in Denver over the weekend says his friends made racist statements about Barack Obama and discussed killing the Illinois Democrat on the day of his presidential nomination acceptance speech.
When asked if he thought his friends were really trying to kill Obama, Nathan Johnson told Denver's KCNC-TV: "Looking back at it, I don't want to say yes, but I don't want to say no."
Johnson was interviewed while in jail on drug charges. He says he wasn't involved in any plot.
Authorities say they're investigating whether Johnson's friend, who was arrested with rifles, ammunition and drugs in his truck, made statements threatening Obama.
But officials also emphasize that the man never posed a "credible threat" to the candidate or to the Democratic National Convention.
FBI spokeswoman Kathy Wright confirms the FBI is investigating.
