DHS Can Enforce. Congress Still Must Reform.

A new hard-line message from America’s top border official says immigration reform is off the table unless Congress finally does its job.

DHS chiefs keep pointing the finger at Congress

For years, leaders of the Department of Homeland Security have told the country that true immigration reform means new laws from Congress, not just policy tweaks from Washington agencies. In 2013, Secretary Janet Napolitano said DHS “welcomes this new Senate immigration bill” and promised to work with lawmakers on a “firm, fair and effective enforcement system,” clearly tying big changes to congressional action. More recently, Secretary Alejandro Mayorkas said bipartisan legislation was needed to give Homeland Security the tools and resources to secure the border and modernize the system.

This pattern crosses party lines and presidents, but the message is the same: Congress writes the rules, and DHS mostly carries them out. Napolitano’s detailed Senate Judiciary testimony framed “commonsense immigration reform” as a mix of tougher border security, employer crackdowns, and a pathway to earned citizenship, but always based on legislation written and passed on Capitol Hill. DHS statements in 2009, 2013, 2021, and 2024 all pair talk of reform with pleas for Congress to act, showing a long history of gridlock that frustrates both officials and citizens.

Enforcement first, reform later: a familiar federal script

Homeland Security bosses have often sold reform by promising tough enforcement first, then limited legalization or worker programs second. In 2007 testimony, Secretary Michael Chertoff said DHS’s reform vision started with “effective control of the border” and a “robust interior enforcement program,” alongside narrow steps for legal workers and some undocumented immigrants. That enforcement-heavy posture set the stage for future debates where border hawks insisted on fences, agents, and deportations before any talk of amnesty, while reform advocates tried to bundle both together.

Later DHS statements under different administrations kept this same balance of slogans and reality. Napolitano highlighted stronger border measures and employer penalties while pushing earned citizenship, trying to reassure both security-minded voters and immigrant families. Mayorkas, serving under a different president, backed executive orders to adjust how asylum and enforcement worked but again pointed to Congress for long-term fixes. These mixed messages helped fuel public confusion, as media clips boiled complex plans down to simple “pro-reform” or “anti-reform” labels.

Legal handcuffs limit what DHS can do alone

Beyond politics, Homeland Security leaders have said federal law itself limits what they can change without Congress. In a 2018 White House briefing, Secretary Kirstjen Nielsen explained that “the laws prohibit us from detaining families” through both prosecution and immigration proceedings and warned that “until these loopholes are closed by Congress, it is not possible, as a matter of law, to detain and remove whole family units” who cross illegally. That statement underlined a key point for conservatives: some of the worst outcomes at the border come from bad laws, not just bad leadership.

Under President Trump’s second term, that legal focus has turned into a clear enforcement pledge. Secretary Kristi Noem said DHS will “fully enforce the Immigration and Nationality Act” and “will not pick and choose which laws we will enforce,” promising no more selective enforcement or backdoor amnesty. At the same time, DHS has described its approach as using limited resources to target threats to national security, public safety, and border security, rather than chasing every single violator in the country. That mix of strict law-and-order language and practical prioritizing shapes how the department handles raids, detention, and removals day to day.

Trump era enforcement meets the Dignity Act debate

President Trump’s agenda has doubled down on enforcement while Congress argues over what “reform” should look like. The White House has ordered the federal government to “faithfully execute the immigration laws of the United States,” framing enforcement as essential to national security and public safety. DHS leaders, first Noem and now Senator Markwayne Mullin as Secretary, have been charged with carrying out that mission even as Democrats push to tie department funding to broad changes in immigration policy.

At the same time, lawmakers from both parties are promoting the Dignity Act of 2025 as a “comprehensive” fix to the broken system. The bill promises to permanently secure the border, modernize asylum, and create legal paths for undocumented immigrants already in the country, while claiming it would reduce the national debt and avoid new taxpayer costs. Its sponsors say the plan pairs strong enforcement, including mandatory employer verification and an end to catch-and-release, with a strict “Dignity Program” that forces long-term illegal residents to pay restitution, pass background checks, and earn legal status without amnesty.

Is reform impossible, or just stuck in Congress?

When Homeland Security Secretary Mullin says “Is immigration reform possible? No,” his comment fits a long record of DHS officials saying their hands are tied without Congress. The department’s public documents back up the idea that agency leaders can adjust priorities, toughen enforcement, and support executive orders, but they cannot rewrite who qualifies for visas, asylum, or citizenship on their own. At the same time, many of those same leaders have supported reform bills in the past, which suggests they see change as difficult and dependent on lawmakers, not truly impossible.

For conservative readers, the core lesson is clear: unelected bureaucrats helped create a mess, but only elected members of Congress can clean up the legal code that drives it. DHS can and should enforce the law, secure the border, and stop illegal crossings and criminal cartels today. Yet until Congress stops playing politics and passes tough, clear reforms that protect citizens, defend the border, and end loopholes, secretaries will keep telling the truth in blunt terms—real immigration reform will not happen.
