Amash's message came shortly after 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!"

The Chicago Tribune reported the numbers Trump referenced.

Trump has ripped Chicago's crime problem in the past, telling Mayor Rahm Emanuel (D) to ask for federal help.

"Chicago murder rate is record setting — 4,331 shooting victims with 762 murders in 2016. If Mayor can't do it he must ask for Federal help!" Trump tweeted earlier this month.

Throughout his campaign, the president promised to bring "law and order" to the country's inner cities.

Amash is a libertarian Republican and the founder of the House Liberty Caucus. He never endorsed Trump during the presidenital campaign, calling him "genuinely terrifying" during the GOP primary and urging the businessman to end his campaign after the October leak of a 2005 tape in which Trump talks about groping women without their consent.
