DHS Investigates 1,620 Voter Fraud Cases with 151 Arrests Amid Nationwide Probe

The Department of Homeland Security (DHS) disclosed on September 19, 2026, that it is currently investigating 1,620 active allegations of voter fraud nationwide, with 151 arrests made so far and an additional 300,000 potential cases under review. The announcement comes as the agency intensifies efforts to safeguard the integrity of upcoming elections, particularly focused on illegal voting by non-citizens.

Scope of the Voter Fraud Investigations

Homeland Security Secretary Markwayne Mullin revealed these figures during an interview with Fox News host Kayleigh McEnany. Mullin emphasized that DHS is actively cross-referencing state public voting registers with federal immigration data to identify instances where non-citizens may have cast ballots illegally. The investigation includes individuals from countries such as Mexico, Nigeria, India, and the Democratic Republic of the Congo, among others.

“This list is only growing,” Mullin said, underscoring the ongoing nature of the probe. The agency is working closely with states to scrub voter rolls and ensure that only legally eligible voters participate in U.S. elections.

Legal Actions and Enforcement Measures

Of the 1,620 active cases, DHS has already arrested 151 individuals suspected of illegally voting. These arrests reflect a broader federal push to enforce stricter penalties against illegal voting, including deportation under the Immigration and Nationality Act. The law mandates removal for aliens who falsely claim U.S. citizenship or illegally cast ballots in elections.

In June 2026, DHS issued a directive requiring Immigration and Customs Enforcement (ICE) to implement tougher enforcement measures against non-citizens committing voter fraud. DHS General Counsel James Percival stated, “Illegal voting by aliens dilutes the votes of American citizens and undermines our democracy. It must have consequences.”

Political Context and Implications for 2026 Midterms

The announcement aligns with the priorities of President Donald Trump’s administration, which has focused on election security and deterring illegal voting in the lead-up to the November 2026 midterm elections. President Trump has repeatedly highlighted concerns about voter fraud, asserting that illegal votes cancel out the ballots of lawful citizens.

Secretary Mullin echoed this viewpoint, saying, “Every single vote that we talk about that was at the hands of an illegal canceled out a citizen that was legally registered and able to vote.” The administration’s efforts reflect a broader Republican emphasis on securing elections and ensuring voter eligibility.

Challenges and Controversies Surrounding Voter Fraud Claims

While DHS continues to pursue cases, critics of voter fraud investigations argue that widespread voter fraud is rare and that aggressive enforcement could suppress legitimate voter participation. However, DHS officials maintain that their actions are necessary to protect the vote’s integrity and uphold democratic principles.

The agency’s ongoing review of hundreds of thousands of potential cases suggests the investigation will remain a significant focus through the remainder of 2026, as election officials and federal agencies work to balance access with security.

As DHS continues to investigate and prosecute cases of voter fraud, the conversation around election integrity remains a key issue in American politics, particularly in states like North Carolina with competitive races on the ballot. The outcome of these efforts could influence public confidence in the democratic process during the critical midterm elections this November.
