In summer 2020, president Trump has authorized the Federal Government to enforce the law against those who vandalize or destroy monuments or other Federal property:
I have authorized the Federal Government to arrest anyone who vandalizes or destroys any monument, statue or other such Federal property in the U.S. with up to 10 years in prison, per the Veteran’s Memorial Preservation Act, or such other laws that may be pertinent..... — Twitter
.....This action is taken effective immediately, but may also be used retroactively for destruction or vandalism already caused. There will be no exceptions!
Further, he has reiterated it:
Anarchists, Agitators or Protestors who vandalize or damage our Federal Courthouse in Portland, or any Federal Buildings in any of our Cities or States, will be prosecuted under our recently re-enacted Statues & Monuments Act. MINIMUM TEN YEARS IN PRISON. Don’t do it! @DHSgov — Twitter
I believe Trump was referring to Public Law 108-29, although I failed to find any reference to "Statues & Monuments Act".
Recently, armed groups of people have broken into a Federal building, apparently destroying and looting Federal property:
From this question and its answers I learned that the United States Capitol Police is responsible for securing law and order in the Federal building of US Capitol.
Question: Assuming that the actions that occurred on January 6th fall under the mentioned law, does the Presidential authorization to enforce this law still active?
