Trump tweeted Tuesday night, "If Chicago doesn't fix the horrible 'carnage' going on, 228 shootings in 2017 with 42 killings (up 24% from 2016), I will send in the Feds!"Chicago Police Superintendent Eddie Johnson responded late Tuesday, saying: "The Chicago Police Department is more than willing to work with the federal government to build on our partnerships with DOJ (Department of Justice), FBI, DEA (Drug Enforcement Administration) and ATF (Bureau of Alcohol, Tobacco and Firearms) and boost federal prosecution rates for gun crimes in Chicago."Mayor Rahm Emanuel criticized Trump on Monday for worrying about the size of the crowd at his inauguration. Emanuel, a longtime political ally of former President Barack Obama, also acknowledged his own frustration with Chicago's crime rate.

Trump isn't offering specifics about how the federal government could help. The White House website says, "Our country needs more law enforcement, more community engagement and more effective policing."8 p.m.

President Donald Trump will begin rolling out executive actions on immigration Wednesday, beginning with plans for building a wall along the US-Mexico border and other enforcement measures, according to two administration officials.

Trump is also expected to roll out plans for restricting refugee flows to the US later in the week.

Trump campaigned on pledges to tighten US immigration policies, including beefing up border security and stemming the flow of refugees. He also called for halting entry to the US from Muslim countries, but later shifted to focus on "extreme vetting" of those coming from countries with terrorism ties.

The officials insisted on anonymity in order to confirm the plans ahead of Trump's official announcement. The president is expected to sign the actions Wednesday during a trip to the Department of Homeland Security.
