A journalist reporting on the pipeline protest has been charged with criminal trespassing.
Court records show Amy Goodman, the host of independent news program ``Democracy Now,'' was charged Thursday and a warrant for her arrest was issued in Morton County.
Goodman reported on a clash between private security guards and protesters during Labor Day weekend.
Some protesters claimed they were attacked by security dogs.
Americas with the Committee to Protect Journalists says the warrant is ``a transparent attempt to intimidate reporters from covering protests of significant public interest.''
