Connor Stevens, Doug Wright and Brandon Baxter -- three men with ties to Occupy Cleveland who were arrested in the spring for plotting to blow up a bridge -- entered guilty pleas on Wednesday afternoon. A fourth man pleaded guilty earlier this year, while a fifth suspect is undergoing a competency evaluation. All three pled guilty to "conspiracy to use a weapon of mass destruction, attempted use of a weapon of mass destruction and attempted use of an explosive device to destroy property used in interstate commerce," according to the DOJ.

“The defendants today made a voluntary choice to plead guilty, the same way they made voluntary choices to try to detonate what they thought were explosive devices they had planted at the foot of a bridge," Steven Dettelbach, U.S. Attorney for the Northern District of Ohio, said in a statement.

“We are pleased these defendants have admitted to their intent to utilize violence, which threatened innocent citizens, to further their ideological views,” said FBI Special Agent in Charge Stephen Anthony.
