Despite recent judicial activism?
That is a clearly unconstitutional decision by a Clinton-appointed district court judge that will ultimately be overturned. The law itself is going to expire on March 5.
There are now over 20,000 sealed indictments awaiting being served. I understand, this is NOT 20K individual persons. Numbers of individuals have multiple indictments against them for specified wrongs. Take either Clinton, or Obunga, or Holder, or Comey, et al; and each one’s numerous crimes.
Yeah...sue Trump to stop the expiration of an unconstitutional order from the previous president?
Don't fall into that semantic trap. DACA is not a law, and never was.
