The crowds, diverse in age and race, also included a group in wheelchairs.

Carrying signs reading "I've seen better cabinets at Ikea" and "Hands 2 small, can't build a wall" the group could only get a block from the Loews Philadelphia Hotel. That's because two large garbage trucks are blocking the intersection.

The congressional delegation is staying at the Lowes Philadelphia Hotel on 12th and Market streets through Friday.

Trump's remarks Thursday in Philadelphia come a day after he began overhauling the nation's immigration system.

After returning to the White House, Trump planned to sign an executive action commissioning a probe into allegations of widespread voter fraud, said White House press secretary Sean Spicer.

Trump planned additional actions on Friday, but Spicer said Thursday that decisions were still to be made on what Trump will sign.
