Democrats are currently withholding funding for the Department of Homeland Security (DHS), prompting former agency leaders to express concern about a possible shift in how Congress intervenes in its operations. John Sandweg, who previously served as acting director of Immigration and Customs Enforcement (ICE), pointed out that while Congress has occasionally given commands to ICE, direct interventions in its operations are rare. “There had been some congressional mandates, some of them through appropriations, some through authorizing statutes that compelled the creation of this system,” Sandweg explained, illustrating the agency’s historical autonomy.
Sarah Saldaña, who directed ICE from 2014 to 2017, mirrored these sentiments by emphasizing that it is unusual for Congress to micromanage how agencies execute their missions. “Congress has a legitimate role in oversight in the expenditure of any taxpayer funds, including ICE’s expenditure, whether it’s proper or not,” Saldaña stated. She highlighted that while Congress can oversee funding, the day-to-day operations remain outside their purview, adding that “They pass statutes.” The congressional focus on ICE’s specific tactics and operations raises important questions about the agency’s independence.
ICE’s operational style has evolved since its establishment in 2003. According to Sandweg, its early years offered some leeway, allowing it to undertake varied enforcement initiatives. However, this flexibility also opened the door for significant policy shifts, particularly during the Trump administration. Lawmakers are now seeking to impose restrictions, including demands to end roving patrols and limit the identification of agents. These proposals come on the heels of heightened scrutiny and concern following tragic incidents involving ICE officers and civilians.
Historically, ICE was formed under the Homeland Security Act of 2002 in response to the September 11 attacks, but it has always faced challenges stemming from its lack of a clear operational framework. Saldaña noted this unique formation, saying, “We’re statutory. We were created after September 11th as a part of all that confusion with respect to intelligence regarding the visa overstays that ended up blowing up the World Trade Center.” Initially, the legislation did not specify ICE by name, leading to an unclear mission as it took on numerous existing immigration functions.
In 2004, Congress began providing funding and directives, allocating $2.1 billion to ICE. Those early directives included mandates for public awareness initiatives and enforcement against child labor. Jessica Vaughan, policy studies director at the Center for Immigration Studies, explained that in the agency’s infancy, immigration enforcement was not a primary focus. “They wanted to devote resources to child sex trafficking and counterfeit goods and gangs while not doing routine immigration enforcement,” Vaughan stated, revealing the internal conflict within ICE’s priorities.
This tension within ICE about its mission continued through subsequent presidential administrations. Sandweg characterized this struggle as a “culture war,” questioning whether to prioritize immigration enforcement or other areas like financial crime investigation. “That second culture took over, the customs culture,” he recalled, highlighting the push and pull of enforcement values within the agency.
Contrarily, Saldaña asserted that immigration enforcement has always remained a clear directive for ICE, albeit shaped differently by each administration’s priorities. “There’s always been a clear mandate,” she contended, underlining that while enforcement strategies might shift, the core mission of immigration enforcement has been persistent.
The escalation of congressional involvement in ICE’s operations can be traced back to frustrations over the agency’s enforcement efforts. For instance, in 2009, lawmakers mandated that ICE maintain a minimum of 34,000 detainee beds, a response to concerns about the perceived leniency in releasing detainees. Vaughan remarked that this increased scrutiny has only reinforced ICE’s enforcement mission, particularly during the Trump presidency. “There has never been a president before Donald Trump who openly valued the immigration enforcement mission as much as he does,” Vaughan affirmed.
As discussions over the DHS budget continue, certain portions of the agency remain unfunded amid the ongoing standoff. ICE, which received substantial funding under Trump’s One Big Beautiful Bill Act signed in July, is engaged in its operations despite the government shutdown. This dynamic highlights the ongoing tug-of-war between legislative oversight and operational independence, reflecting a critical juncture for how immigration enforcement will be shaped in the years to come.
