Late last week the U.S. House voted to “withhold certain federal law enforcement grants to cities that have policies designed to shelter illegal immigrants from deportation,” Cristina Marcos reported for The Hill. The “Enforce the Law for Sanctuary Cities Act” passed on a mostly party-line vote of 241 to 179 (roll call). Iowa Republicans Rod Blum (IA-01), David Young (IA-03), and Steve King (IA-04) voted for the bill, while Democrat Dave Loebsack (IA-02) voted against it.

King is a leading voice for House conservatives on immigration policy, some of whom wanted the sanctuary cities bill to go further. House Majority Leader Kevin McCarthy helped bring the Iowa Republican on board last week by promising “to bring enforcement immigration legislation to the floor after August,” Seung Min Kim reported for Politico, citing an e-mail King sent to fellow House members. What a change from two years ago, when King was battling to stop House leaders from bringing up the Senate-approved comprehensive immigration reform bill.

Senator Chuck Grassley has introduced legislation in the upper chamber to target “sanctuary cities” and presided over a Senate Judiciary Committee hearing to discuss his bill on July 21, Mike Lillis reported. “There is no good rationale for noncooperation between the feds and state and local law enforcement,” according to Grassley. A White House statement indicated that President Barack Obama would veto such legislation and urged Congress to give the president’s 2014 executive orders on immigration “a chance to work,” because they prioritize deporting “the worst offenders”–in contrast to the “coercive approach” of the House bill on sanctuary cities.

The term “sanctuary city” has no precise legal definition. No Iowa municipality has embraced the label, although Iowa City officials have considered the issue in recent years. Some maps of sanctuary cities do not show any existing in Iowa, while others list many Iowa locations where county officials will not honor a detainer from U.S. Immigrations and Customs Enforcement without a judge’s approval. Incidentally, that policy doesn’t just apply to a few liberal enclaves; county jails in rural, conservative areas like Ida, Monona, Greene, and Franklin counties have adopted the same approach.

UPDATE: Forgot to mention that in June, King offered an amendment to the Justice Department appropriations bill that “prohibits Justice Department grants from being used for policies employed by sanctuary cities to shelter illegal immigrants.” King’s amendment passed with support from fellow Iowa Republicans Blum and Young; Loebsack and every other Democrat present voted against it.
