DENVER - The Associated Press

Authorities are investigating whether a man arrested with rifles, ammunition and drugs in his truck made statements threatening Barack Obama, but emphasize he never posed a "credible threat" to the presidential candidate or the Democratic National Convention.
Federal and local authorities had scheduled a news conference for Tuesday afternoon, but U.S. Attorney Troy Eid downplayed the case.
"We're absolutely confident there is no credible threat to the candidate, the Democratic National Convention, or the people of Colorado," Eid said in a statement.
FBI spokeswoman Kathy Wright confirmed the FBI was investigating reports the man had threatened Obama, who will be in Denver this week to accept the Democratic nomination for president. The Joint Information Center � a command set up by city, state and federal authorities to field media inquiries during the Democratic convention - said it had no immediate comment.
The action started around 1:30 a.m. Sunday when police in the eastern suburb of Aurora stopped a truck that was swerving erratically. The driver, 28-year-old Tharin Gartrell, had a suspended driver's license, and the truck was rented in the name of another person, said Aurora police Detective Marcus Dudley.
In the truck, officers found two rifles, including one with a scope; a bulletproof vest; boxes of ammunition; walkie-talkies; and suspected narcotics, Dudley said.
