WASHINGTON (AP) — Amid a violent shooting incident involving two National Guard members near the White House, President Donald Trump pronounced the attack as evidence that loose immigration policies pose 'the single greatest national security threat' to the country. In a direct message aimed at reshaping immigration, Trump expressed, 'No country can tolerate such a risk to our very survival.'

The shooter, identified as an Afghan national, entered the United States in September 2021 during the chaotic withdrawal from Afghanistan while the Taliban reclaimed power. Trump seized on this as a talking point to underline his commitment to more stringent immigration vetting processes.

The 29-year-old suspect is reportedly part of Operation Allies Welcome, the initiative aimed at resettling Afghans who had worked with U.S. troops. As this program faces increasing scrutiny, Trump and his allies are calling for reviews of vetting protocols to eliminate gaps that critics argue have compromised safety.

Trump's comments reveal a multi-pronged strategy of ramping up deportation efforts for undocumented migrants while simultaneously curbing the admission of refugees. Administration officials are aligning federal resources to achieve these goals, stirring concerns of lost focus on other law enforcement priorities.

The response from immigrant advocates has been sharply critical. The increase in scrutiny raises fears for the tens of thousands of Afghan nationals seeking safety and a fresh start in America. In an alarming development, U.S. Citizenship and Immigration Services announced a halt on all immigration requests from Afghan nationals pending reviews of security protocols.

Critics, including advocates for Afghan evacuees, caution against political exploitation of the shooting. They stress that the incident shouldn't overshadow the significant contributions of Afghan refugees who have legitimately sought asylum in the U.S.

With the nation’s immigration landscape shifting under Trump's proposals, the uncertain future of Afghan nationals remains a point of contention, amid increasing demands for stringent immigration policies across the board.
