CHICAGO (AP) — The sight of armed, camouflaged and masked Border Patrol agents making arrests near famous downtown Chicago landmarks has amplified concerns about the Trump administration’s growing federal intervention across U.S. cities.

As Illinois leaders warned Monday of a National Guard deployment, residents in the nation’s third-largest city met a brazen weekend escalation of immigration enforcement tactics with anger, fear and fresh claims of discrimination.

“It looks un-American,” said Chicago Alderman Brendan Reilly, who represents downtown on the City Council. He deemed the Sunday display a “photo op” for President Donald Trump, echoing other leaders.

Memphis, Tennessee, and Portland, Oregon, also braced for a federal law enforcement surge. Meanwhile, Louisiana’s governor asked for a National Guard deployment to New Orleans and other cities.

Trump has called the expansion of federal immigration agents and National Guard troops into American cities necessary, blasting Democrats for crime and lax immigration policies. Following a crime crackdown in the District of Columbia and immigration enforcement in Los Angeles, he’s referred to Portland as “war-ravaged” and threatened apocalyptic force in Chicago.

“Whether it takes place here in the city or the suburbs, it’s all the same to us,” Border Patrol agent Gregory Bovino said in Chicago.

Attorney General Pam Bondi has issued a memo that also directs component agencies within the Justice Department, including the FBI, to help protect U.S. Immigration and Customs Enforcement facilities, including in Chicago and Portland.

Many Chicagoans were already uneasy after an immigration crackdown began earlier this month. Agents have targeted immigrant-heavy and largely Latino areas.

Trump has waffled on sending the military, but Democratic Gov. JB Pritzker said Monday it appeared the federal government would deploy 100 troops. Pritzker said the Illinois National Guard received word that the Department of Homeland Security sent a memo to the Defense Department requesting troops to protect ICE personnel and facilities.
