More than 4,500 people have been arrested nationwide as President Donald Trump's promised crackdown on undocumented immigrants appears to ramp up.

The hardliners' opposition -- and concern about the nation's growing $36 trillion debt, which Congress will need to act on this year -- could block the tax cut plan in a House where Republicans hold a slim 218-215 majority that is expected to fall soon to 217 seats.

The Immigration and Customs Enforcement (ICE) conducted raids in New York on Tuesday in search of undocumented immigrants. The operation was supported by the local police, according to NBC. The actions of Donald Trump's administration are causing significant controversy.
