Lawmakers representing Hispanic communities across the country are demanding answers from the Department of Homeland Security following a series of U.S. Immigration and Customs Enforcement operations that led to hundreds of arrests in multiple states last week — so far, the elected officials say, they aren’t getting them.

On Tuesday, ICE’s acting director, Thomas Homan, cancelled a meeting with members of the Congressional Hispanic Caucus in which he was to provide details on the more than 680 people arrested across the country last week and explain the guidance given to his agents in conducting the operations.

ICE had described the operations as “routine,” but when Rep. Michelle Lujan Grisham, head of the Hispanic caucus, called the ICE chief following the cancellation of yesterday’s meeting, she learned that was not exactly the case.

“He confirmed that there’s a shift in policy but did not give me the details about what that means,”Lujan Grisham told The Intercept.

Lujan Grisham added that Homan also “confirmed that that shift in policy has made its way to all of the local ICE agents” and said the ICE director indicated the cancellation of yesterday’s meeting was the result of directions from his superiors — meaning DHS Secretary John Kelly or the White House.

ICE and the White House did not respond to requests for comment. DHS, meanwhile, denied that the cancellation was ordered from Washington. In a statement to The Intercept, DHS press secretary Gillian M. Christensen said, “ICE leadership agreed to meet with six Democratic Members of Congress who signed a request on Monday, February 13, with the purpose of updating them on ICE’s recent enforcement operations. Because the attendees’ list grew substantially, DHS reached out to the House leadership staff to arrange a bipartisan, in-depth briefing, which the Speaker’s office arranged and scheduled for Thursday of this week.”

“ICE looks forward to sharing information on its enforcement operations and how they are humanely and professionally enforcing U.S. immigration law,” Christensen added.

While ICE conducted similar raids under the Obama administration, new executive orders on domestic immigration enforcement signed by President Trump have radically expanded the universe of individuals prioritized for deportation. While he did not get into details, Grisham said, Homan did confirm that the shift in policy is in accordance with Trump’s executive order — DHS did not address questions related to orders.

That shift is significant, lawmakers and advocates say, because Trump’s directives effectively make every undocumented person in the country a target for removal.

Lujan Grisham first revealed the details of the conversation in a press conference Tuesday afternoon — in which Rep. Grace Napolitano called the government’s stated justification for canceling the meeting as “bullshit”— and elaborated on the information in an interview with The Intercept Wednesday morning. She explained that the “real shift” in Trump’s executive order is found in its “broader language and discretion.” Under the order, undocumented individuals who are suspected of having committed an offense that could constitute a crime can be deported, even if they are never convicted or even charged.

“This is really chilling in terms of what the potential intent here is, particularly if you match it to the Trump campaign — ‘we’re going to deport everyone who’s here illegally,’”Lujan Grisham said. “Are we starting that?” she asked. “I, we, won’t know, until we can get the details of every person who’s been arrested.”

ICE has reportedly circulated written guidance to its agents on implementation of Trump’s order. Obtaining that guidance,Lujan Grisham said, is critical for the public to understand exactly where the immigration enforcement agency’s priorities lie — DHS did not comment on the existence of the guidance when asked if it would be handed over to lawmakers. In a statement Monday, DHS Secretary Kelly said 75 percent of those arrested were “criminal aliens.” While Kelly pointed to a number of serious, violent offenses committed by some of those arrested, there was no comprehensive breakdown of the alleged violations among the arrestees, and the term criminal alien is broad enough to include a whole host of low-level, nonviolent offenses.

“Is it individuals with false identification to work?”Lujan Grisham asked. “Is it individuals who were deported? Moms who came back to unite with their American-born, citizen children? I don’t know what he means by that 75 percent.”
