U.S. Immigration and Customs Enforcement violated Jeanette Vizguerra’s First Amendment rights by detaining — and planning to deport — the Colorado immigration advocate, her attorneys argued in federal court in Denver on Friday.

Attorneys for immigrant activist Jeanette Vizguerra claim she was "targeted" and detained by immigration officials "for her activism, for her open speech about the process, and for her organizing."

An undocumented mother and high-profile activist was detained by ICE while she was on a work break from her job at Target, her attorney and a family friend say.
