Two senators and, a congresswoman and a congressman issued statements Friday demanding action in the wake of the arrest of Carlos Bolanos.

Sen. Ron Wyden (D), Sen. Jeff Merkley (D), Rep. Suzanne Bonamici (D) and Rep. Earl Blumenauer (D) all want to know how U.S. Immigration and Customs Enforcement will respond to a video, taken by George Cardenas, showing plainclothes officers arresting Bolanos in a Portland home without a warrant or consent to enter.

When Cardenas tells them need a warrant, the agent doing most of the communicating tells Cardenas he does not need a warrant, because the home is a place of business. Legal experts said Friday that is not true and that either consent or a warrant should have been required to enter the home.

The agents later arrested, and then released, Bolanos. An ICE spokesperson said the agency was looking into the incident.

Now, Oregon's lawmakers are responding to what they see as a pattern of behavior by ICE agents.

"Exactly one month ago, I demanded an investigation after a U.S. citizen was mistreated by ICE agents," Blumenauer said in a statement Friday.

"ICE's response was misleading at best, and failed to take responsibility for any of the actions necessary to correct what is a clear pattern of inappropriate behavior by the agency," Blumenauer continued. "I'm glad that it appears an investigation is underway regarding this most recent case, but there should have been one a month ago. I hope ICE will expand its investigation beyond this specific case. People must be held accountable."

Wyden and Merkley sent a joint letter to Elizabeth Godfrey, acting field office director of the ICE Seattle office.

"Americans do not lose their constitutional protection from warrantless search and seizure simply because ICE believes they may be immigrants," reads the letter. "The actions of the ICE agents involved in Mr. Bolanos' arrests are counter to the very policies and practices the Department of Homeland Security claims to uphold."

Wyden and Merkley asked Godfrey to provide them with a copy of the results of review of the incident, as well as "a clear explanation into the policies and practices that led to Mr. Bolanos' arrest" and an explanation about "whether the behavior demonstrated by ICE agents who detained Mr. Bolanos is consistent with agency guidelines."

They also asked what measures have been initiated to correct the "inappropriate and potentially unlawful behavior" of the agents.

Bonamici and Blumenauer also wrote a letter to Godfrey and ICE Acting Director Thomas Homan.

"Director Godfrey emphasized the need for public trust in law enforcement and the ICE agency," that letter read. "We share that goal, but these two recent examples of inappropriate behavior by ICE agents are serious threats to people we represent, and they undermine public confidence in the integrity of the agency."
