A day after he used a "softer tone" for Donald Trump," New York City Mayor Bill de Blasio straight up told the new president-elect that New York is going to resist his plans for illegal immigration. Speaking at City Hall on Thursday, the mayor said the city is not going to take any of President Trump's controversial plans "lying down."

“Anything we see as a threat to New Yorkers we will confront,” he insisted.

Trump's immigration plan is one of those perceived threats. The president-elect's proposal to subject illegal immigrants to deportation is apparently still part of the plan, according to his official website.

Not in New York, De Blasio insists.

“We are not going to sacrifice a half million people who live among us,” he said. “We’re not going to tear families apart. We will do everything we know how to do to resist that.”

The liberal New York mayor is one of several leaders who will undoubtedly try to resist the newly elected president and his policies, considering he made more than a few enemies during the 2016 campaign with his non-PC behavior.

Both President Obama and Hillary Clinton, however, urged Americans to come together and support their new president.
