Protesters are expected to gather in Center City for several rallies Friday and Saturday, capping a busy week of demonstrations across the region.

The biggest, the March for Humanity, is scheduled from 1 to 4 p.m. Saturday at Thomas Paine Plaza, across from City Hall. The event aims to counter President Trump's executive order banning refugees and immigrants from seven primarily Muslim countries.

"We will not stand by quietly after the executive order that bans refugees and immigrants from seven Muslim countries [Syria, Iraq, Iran, Libya, Somalia, Sudan, and Yemen]," says the event description on Facebook, where thousands of people have expressed interest in the event. "We oppose the ban and any other action that harms our communities or treats people with indignity."

Trump's inauguration, and especially the executive order on immigration signed Jan. 27, have sparked a surge in protest activity in Philadelphia. Thousands of people protested outside the president's appearance at last week's GOP congressional retreat in the city, and thousands more gathered at Philadelphia International Airport last weekend to protest the order and the detainment of immigrants flying into Philadelphia.

A smaller demonstration against the Dakota Access Pipeline is set to take place Friday afternoon outside the Wells Fargo Building at 123 S. Broad Street in protest against the bank's investment in the project.

Also Friday afternoon, Philadelphia educators are planning to gather outside Republican Sen. Pat Toomey's Philadelphia office to press him to vote against the nomination of Betsy DeVos for education secretary.

In yet another Friday afternoon demonstration, a group of Philadelphia School District students and others are planning to rally at City Hall to support immigrant and Muslim students across the city.

SEPTA is urging riders to use subway and trolley routes for travel in Center City on Saturday.

Other protests this week included hundreds of Comcast employees speaking out against Trump's immigration policies; an anti-Trump group led by LGBT rights and Black Lives Matter advocates marching in Center City; and activists protesting, mainly against Toomey, outside a GOP fund-raiser in Drexel Hill.
