Washington: Dozens of protesters on Saturday delayed a rally by Republican presidential frontrnner Donald Trump in the Phoenix suburbs.

The protesters were carrying signs denouncing racism. They delayed the rally by blocking an Arizona highway leading to the rally site.

The protesters first blocked the highways using a pair of pickup trucks decorated with banners reading "Comb Over Racism: Dump Trump" and "Shut Down Trump." Some protesters blocked the roadway, carrying signs reading "Love Trumps Hate" and "Stand Against Racism." One homemade sign said, "Combat White Supremacy."

The police arrived at the highway and towed away the trucks. The protesters then formed a human wall. Traffic on the highway resumed after officers started arresting protesters.

Later Saturday afternoon, some protesters tried to block the entrance to the Tucson Convention Center, chanting "Shut it down!". The protesters also tried to stop Trump supporters from entering a rally called by the billionaire businessman.

In New York City, protesters from a several left-leaning organizations joined hands to organize a roaming protest on Saturday. The protesters targeted two of Trump's most prominent properties in midtown Manhattan. Police reportedly used used tear gas in order to stop some protesters from moving past barriers near Trump Tower on Fifth Avenue.

Trump's critics have expressed hope that the protests across the country would hurt Trump's chances of becoming the Republican presidential nominee, but Trump supporters claimed the videos and images of these protests will help the billionaire businessman ahead of Tuesday's primary in Arizona and caucuses in Utah. As police tried to remove the protesters from the highway, many Trump supporters waited in the sun for their leader to arrive at Fountain Park.

Maricopa County Sheriff Joe Arpaio, whose jurisdiction includes Fountain Hills, introduced Trump and announced that three protesters have been arrested. "We had a little problem - some demonstrators were trying to disrupt," said Arpaio. "If they think they're going to intimidate you and the next president of the United States, it's not going to happen. Not in this town, I'll tell you right now," he added.
