The head of the union for U.S. Immigration and Customs Enforcement agents sent a letter to President Obama on Tuesday asking to be included in future meetings he has on immigration after the agents were left out of White House talks with business groups and immigrant-rights activists.

Chris Crane, president of the 7,000-member National ICE Council, said it was troubling that Mr. Obama had met with those pushing for legalization but the president hadn’t asked the agents responsible for enforcing the laws to take part.

“These measures would have significant implications for interior immigration enforcement and I believe our officers — who risk their lives every day to secure the nation — have a crucial perspective to offer,” Mr. Crane said in the letter, a copy of which was provided to The Washington Times.

Mr. Crane is scheduled to testify before the Senate Judiciary Committee on Wednesday, and he testified before the House Judiciary Committee last week.

But he has not been included in the meetings the White House has hosted for business groups, Hispanic members of Congress, immigrant-rights activists and others who are backing the president’s push for legalizing the estimated 11 million illegal immigrants in the U.S.
