s in Border Crossings
Since President Trump resumed office, the number of unlawful border crossings along the U.S.-Mexico frontier has dropped to the lowest point in decades, driven heavily by unprecedented cooperation from the Mexican government. Yet, for one of the administration’s most influential policy architects, those historic reductions are still not enough.
In private conversations with both American and Mexican officials over the last several months, Stephen Miller has repeatedly insisted that illegal border crossings must be reduced even further, according to officials in both countries familiar with the discussions who were not authorized to speak publicly. Mr. Miller’s ultimate objective, these officials said, is a standard of absolute zero unauthorized entries. Mexican officials, however, have pushed back against the demand, arguing that securing a dynamic, nearly 2,000-mile international border to that absolute standard is simply not feasible.
As Mr. Miller transitions fully into his new role as White House chief of staff, he is widely expected to continue driving this hardline agenda, maintaining intense pressure on diplomatic and domestic channels alike.

One of the primary forums for Mr. Miller’s hardline demands has been his near-daily calls with the U.S. ambassador to Mexico, Ronald Johnson, according to several officials. During these calls and in subsequent strategy sessions with administrative staff, Mr. Miller, who previously served as the deputy chief of staff, frequently rails against the ongoing volume of border crossings. This intense scrutiny has persisted despite the fact that overall crossing figures remain at historic lows compared to previous years.
The insistence on near-total eradication of unlawful entries has taken on a renewed urgency in recent months, officials noted. During this period, border crossings experienced a slight upward tick, reaching the highest point recorded thus far during President Trump’s second term. While these numbers remain a fraction of the migration surges seen in past years, the modest increase has served to amplify pressure from the upper echelons of the West Wing.
The dynamic underscores the ongoing tension between Washington’s uncompromising immigration enforcement goals and the logistical and geographical realities managed by Mexican authorities. Mexico has deployed significant national resources to intercept migrants traveling northward, successfully dismantling numerous smuggling networks and drastically slowing the overall flow of people reaching the U.S. border.
At major ports of entry, such as the San Ysidro crossing in Tijuana, policy shifts and joint enforcement efforts in previous periods had driven unlawful crossing metrics down to as few as 150 to 200 per day—a stark contrast to the thousands daily recorded during peak migration periods of prior administrations.
Nevertheless, administration officials close to the policy-making process maintain that any level of unauthorized migration remains unacceptable to the White House leadership. With Mr. Miller now directing operations from the chief of staff’s office, the administration’s posture toward regional partners and border enforcement agencies signals that the pressure on Mexico to curb migration will remain unrelenting, even as bilateral friction over the definition of border security continues.
