"Not my President": Protesters target Trump buildings in massive rallies

Donald Trump's victory in the U.S. elections is an outcome several Americans are just refusing to accept, as protests have broken out across the country in which at least 25 US cities overnight had demonstrations outside Trump's properties.

While most protesters were peaceful, dozens were arrested and at least three officers were wounded. And about 40 fires were set in one California city, reports CNN.

On Thursday afternoon, more than 200 anti-Trump protesters marched from the Union Square area to Washington Square Park in Manhattan.

Some carried signs with messages such as, "White men stop ruining everything." They chanted, "Trump and Pence make no sense."

Overnight, about 5,000 people protested the real estate mogul's victory outside Trump Tower, authorities estimated, this included pop star Lady Gaga who is a firm Hillary Clinton supporter.

The concern of the protestors ranged from policies, such as Trump's proposed plan to build a wall along the US-Mexican border, to the polarizing tenor of his campaign that they say stoked xenophobic fears.

At least 15 protesters at Trump Tower were arrested Wednesday night for disorderly conduct, New York police said.
