Earlier in the day, thousands of people gathered at Thomas Paine Plaza outside City Hall and marched in the vicinity to oppose the president's sweeping agenda, which includes repealing the Affordable Care Act, stripping federal funding from sanctuary cities like Philadelphia, advancing the Keystone XL and Dakota Access pipeline projects, and constructing a wall along the southern border of the United States.
Protests that began on Wednesday night, many marked by signs and chants against the new administration, grew significantly on Thursday as Trump delivered an address to GOP leaders inside the Loews Philadelphia Hotel.
But those who marched in Center City pushed back against the substance of that vision, large parts of which have divided Americans throughout Trump's provocative presidential run and into his first days in office. Below are scenes from Thursday night's protests.
