Former President Barack Obama warned of “dangerous trends” emerging from the Trump administration, saying its policies “put the liberties of all Americans at risk.”

On X, Obama cited an interview with Ezra Klein of The New York Times and a journalist on “The Ezra Klein Show,” during which they discussed President Donald Trump’s threat to send National Guard troops into New York and Chicago, the former president’s hometown.

“This interview, which is also available as a podcast, provides a useful overview of some of the dangerous trends we’ve been seeing in recent months regarding federalization and militarization of state and local police functions,” Obama wrote on X.

“The erosion of basic principles like due process and the expanding use of our military on domestic soil put the liberties of all Americans at risk and should concern Democrats and Republicans alike,” he added.

Trump has suggested launching a federal crackdown to combat crime in Chicago, similar to what is happening in Washington, D.C.

“Governor Pritzker had 6 murders in Chicago this weekend,” Trump wrote Thursday on Truth Social, referring to Illinois Gov. JB Pritzker. “Twenty people were shot. But he doesn’t want to ask me for help. Can this be possible? The people are desperate for me to STOP THE CRIME, something the Democrats aren’t capable of doing. STAY TUNED!!! President DJT.”

Threats to send in the National Guard to help combat crime in blue cities have elicited outrage from Democrats.

Earlier in the week, Trump criticized Pritzker and Chicago Mayor Brandon Johnson over the city’s crime rate. The governor has said he will resist any federal intervention.

“I say, ‘Mr. President, do not come to Chicago. You are neither wanted here nor needed here,”‘ Pritzker told reporters this week.
