WASHINGTON (AP) The video shared by former President Donald Trump features horror movie music and footage of migrants purportedly entering the U.S. from countries including Cameroon, Afghanistan and China. Shots of men with tattoos and videos of violent crime are set against close-ups of people waving and wrapping themselves in American flags.

Theyre coming by the thousands, Trump says in the video, posted on his social media site. We will secure our borders. And we will restore sovereignty.

In his speeches and online posts, Trump has ramped up anti-immigrant rhetoric as he seeks the White House a third time, casting migrants as dangerous criminals poisoning the blood of America. Hitting the nations deepest fault lines of race and national identity, his messaging often relies on falsehoods about migration . But it resonates with many of his core supporters going back a decade, to when build the wall chants began to ring out at his rallies.

President Joe Biden and his allies discuss the border very differently. The Democrat portrays the situation as a policy dispute that Congress can fix and hits Republicans in Washington for backing away from a border security deal after facing criticism from Trump.

But in a potentially worrying sign for Biden, Trumps message appears to be resonating with key elements of the Democratic coalition that Biden will need to win over this November.

Roughly two-thirds of Americans now disapprove of how Biden is handling border security, including about 4 in 10 Democrats , 55% of Black adults and 73% of Hispanic adults, according to an Associated Press-NORC Center for Public Affairs Research poll conducted in March .

A recent Pew Research Center poll found that 45% of Americans described the situation as a crisis, while another 32% said it was a major problem.

Vetress Boyce, a Chicago-based racial justice activist, was among those who expressed frustration with Bidens immigration policies and the citys approach as it tries to shelter newly arriving migrants. She argued Democrats should be focusing on economic investment in Black communities, not newcomers.

Theyre sending us people who are starving, the same way Blacks are starving in this country. Theyre sending us people who want to escape the conditions and come here for a better lifestyle when the ones here are suffering and have been suffering for over 100 years, Boyce said. That recipe is a mixture for disaster. Its a disaster just waiting to happen.

Gracie Martinez is a 52-year-old Hispanic small business owner from Eagle Pass, Texas, the border town that Trump visited in February when he and Biden made same-day trips to the state . Martinez said she once voted for former President Barack Obama and is still a Democrat, but now backs Trump mainly because of the border.

Its horrible, she said. Its tons and tons of people and theyre giving them medical and money, phones, she said, complaining those who went through the legal immigration system are treated worse.

Priscilla Hesles, 55, a teacher who lives in Eagle Pass, Texas, described the current situation as almost an overtaking that had changed the town.

We dont know where theyre hiding. We dont know where theyve infiltrated into and where are they going to come out of, said Hesles, who said she used to take an evening walk to a local church, but stopped after she was shaken by an encounter with a group of men she alleged were migrants.
