Three men have been charged with plotting to attack President Barack Obama's campaign headquarters and throw Molotov cocktails at police on the eve of a NATO summit.
Police insisted there were no imminent threats to the leaders of more than 50 countries that will meet at the two-day summit in Chicago.
At a May 19 hearing, prosecutors said the three young men were self-described anarchists who had boasted weeks earlier about the damage they would do in Chicago.
The men allegedly bought fuel at a gas station for the makeshift bombs and poured it into beer bottles before being arrested by police.
If convicted on all counts -- conspiracy to commit terrorism, material support for terrorism, and possession of explosives -- the men could get up to 85 years in prison.
