Thousands of 'No Kings Day' protests are expected to take place across the nation Saturday, with the 'flagship' protest planned for Philadelphia.

Parker's comments indicate the city will take an assertive approach toward unlawful activity that occurs alongside peaceful protests on Saturday.

Philadelphia was chosen in part because it is where the Second Continental Congress signed the Declaration of Independence.

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Philadelphia is among five Democratic-led cities where President Trump is preparing to send ICE tactical teams ahead of nationwide protests.
