It now appears that three men who authorities initially feared were plotting to assassinate Barack Obama at the Democratic National Convention will face only gun charges.
A federal law enforcement official says the three men as well as a woman arrested on Sunday are not expected to be charged with making threatening statements, conspiracy or other national security-related crimes.
The official says it's possible -- but unlikely -- that additional charges could come later.
1 of the men was arrested near Denver with two rifles, ammunition, walkie-talkies and suspected drugs. Federal officials say the other two men and the woman were apprehended a few hours later.
The likelihood of an assassination plot against Obama is being downplayed by law enforcement officials in Colorado and Washington.
