Trump Threatens Anyone Caught Vandalizing Federal Statues With Ten Years In Prison
"I have authorized the Federal Government to arrest anyone who vandalizes or destroys any monument, statue or other such Federal property in the US with up to 10 years in prison, per the Veteran’s Memorial Preservation Act," the president said in a tweet on Tuesday.
.....This action is taken effective immediately, but may also be used retroactively for destruction or vandalism already caused. There will be no exceptions!
