While the U.S. federal government sent the National Guard to the city of Chicago, Illinois, U.S. President Trump said on social media on October 8, that Democratic Chicago mayor Johnson and Illinois governor Pritzke should be put in jail.

Trump posted on social media early on the 8th:"The mayor of Chicago should be put in prison for failing to protect U.S. Immigration and Customs Enforcement officials! So is Governor Pritzker!"

According to US media reports on the 7th, the Trump administration has sent the National Guard to Illinois, and the first batch of 200 Texas National Guard members arrived in the Chicago area that day.

Illinois and the city of Chicago filed a lawsuit against the Trump administration on the 6th, trying to prevent it from deploying the National Guard to Chicago. Johnson reiterated on the 7th that deploying National Guard personnel to Chicago was "illegal, unconstitutional, dangerous and wrong." Pritzker reposted on social media that Chicago has been the "Best Big City in the United States" for nine consecutive years.

Chicago, the largest city in Illinois, and the third largest city in the United States, Trump criticized Chicago in early September, calling it the ¡°worst and most dangerous¡± city in the world, and said he would deploy the National Guard to ¡°fight crime¡± in the city.
