New York: More than 1000 protesters converged in midtown​ Manhattan on Monday evening, marching, chanting and waving signs before US President Donald Trump's first return to his Fifth Avenue penthouse since taking office.

The demonstrators, who lined several blocks outside Trump Tower and also gathered just south near Bryant Park, were determined to give the President a discordant welcome home. Many people said recent events that caused alarm - the deadly white nationalists' rally in Virginia; Trump's tepid condemnation of it; and his threats of "fire and fury" toward North Korea - inspired them to show up.

"Every week it's something new," said Michael Wang, a 36-year-old artist and consultant in New York who was holding a sign outside Trump Tower that read, "Nuclear war is not a ratings game."

The groups began to gather around 5Pm, filling sidewalks and disrupting normal traffic near Trump Tower, erupting at times into clashes with police officers. Dozens of officers formed a single-file wall outside Trump Tower, and some unruly protesters were yanked from the crowd.
