Mexico City residents aren’t happy with Americans that have moved to their city and made things more expensive, demanding they leave, the Los Angeles Times reported Wednesday.

A growing number of Americans from areas like Silicon Valley and Brooklyn, New York, have flocked to the city, taking advantage of its beauty and cheap rent, according to the LA Times. The issue is expected to worsen with rising inflation as more Americans look for affordable alternatives.

Washington, D.C., Mayor Muriel Bowser has requested that the D.C. National Guard be activated indefinitely to respond to migrant buses arriving in the district, according to reports.

The request also seeks permission to use the D.C. Armory, a multipurpose arena located east of the Capitol Building, as a processing center, as more than 150 buses traveling from Arizona and Texas have transported nearly 4,000 migrants to the nation’s capital over the past three months. Bowser and the D.C. Homeland Security and Emergency Management initially sent letters to the Office of the Secretary of Defense in a letter on July 19 and to President Joe Biden on July 22. Neither letter has received an answer, according to NBC.

“The pace of arriving buses and the volume of arrivals have reached tipping points,” Bowser wrote. “Our collective response and service efforts have now become overwhelmed. … Tragically, many families arrive in Washington, DC with nowhere to go, or they remain in limbo seeking onward destinations across the United States.”

Since mid-April, more than 125 buses have transported 4,800 migrants from Texas border communities — such as the Rio Grande Valley, Del Rio, Uvalde, and Eagle Pass — nearly 2,000 miles to Washington. Gov. Doug Ducey (R-AZ) commenced a similar initiative in mid-May and has had 27 buses carrying more than 1,000 passengers from the border to D.C. in that time, according to spokeswoman Morgan Carr.

However, D.C. officials such as Bowser have decried the move, claiming immigrants are being “tricked” into traveling farther away from their intended destinations.

“With pledges from Texas and Arizona to continue these abhorrent operations indefinitely, the situation is dire, and we consider this a humanitarian crisis — one that could overwhelm our social support network without immediate and sustained federal intervention,” Bowser wrote.

Because immigration is a federal issue, Bowser argued, the federal government must provide “immediate federal assistance.” As a result, the mayor requested the Office of the Secretary of Defense to initiate a Joint Reception, Staging, Onward Movement, and Integration mission that would provide 150 personnel to the district to transport migrants to a temporary processing center at the DC Armory.
