New York City Mayor Bill de Blasio unveiled his plan to sue the Trump administration over the President’s latest proposal to relocate detained illegal immigrants to Sanctuary Cities across the US; calling the policy “just plain illegal.”

“It’s illegal. It is just plain illegal. We will meet him in court. We will beat him in court,” De Blasio told NY1.

The Big Apple Mayor’s comments are in stark contrast to other liberal leaders across the country who embraced the President’s proposal.

“The city would be prepared to welcome these immigrants just as we have embraced our immigrant communities for decades,” said Philadelphia Mayor Jim Kenney.

“As a welcoming city, we would welcome these migrants with open arms, just as we welcomed Syrian refugees, just as we welcomed Puerto Ricans displaced by Hurricane Maria,” added outgoing Chicago Mayor Rahm Emanuel.
