In a speech at the Community College of Philadelphia, Mayor James Kenney (D) said he is "hopeful but cautious" regarding the changes President-elect Donald Trump will institute at the federal level.

Kenney, who had endorsed Hillary Clinton, said he will cooperate with Trump's administration in "any [way] that is positive", but warned that he will not sacrifice his position on a series of issues, the Philadelphia Inquirer reported.

Changes in policies on the protection of minorities, LGBT rights and the safety of the immigrant community are off the table, Kenney said.

"We're not walking back on [our] sanctuary city [policy or] on anything we've established to make our city progressive," he said.

Philadelphia is one of a number of large cities, including Newark, N.J., New York, San Francisco, Washington, D.C., and Chicago that have pledged not to cooperate with federal immigration enforcement in the deportation of persons residing in the United States illegally.

Trump has repeatedly said he will cut federal funding to cities that act as a safe haven for illegal immigrants.

Kenney pointed to the Fourth Amendment, which ensures the right of people to be secure against unreasonable searches and seizures, saying that Philadelphians cannot be held against their will without a court warrant.
