US President Donald Trump is set to visit the two cities still reeling from the two mass shootings last weekend. Thirty-one people were killed in the attacks in El Paso, Texas, and Dayton, Ohio. Scores more were wounded. And while the communities are grieving, some politicians in both cities say the president isn't welcome. CGTN's Dan Williams reports.

A mountain of flowers, messages and candles. A symbol of the heartbreak and devastation calls for the mass shooting in El Paso on Saturday. The city's hospitals continue to treat those wounded in the attack. Some of the survivors still coming to terms with the horror.

CHRISTOPHER GRANT EL PASO ATTACK SURVIVOR "We were gong to the store to get groceries for the kids. It just went chaotic as soon as we got there. My mum was in the produce department. I was in the drinks department. And then I heard the gunshots."

Across the city at a local school, a memorial was held for 15-year-old Javier Rodriguez. Friends and family overcome in grief.

HAYLEY MARTINEZ FRIEND OF JAVIER RODRIGUEZ "It's so hard to know that he's gone and just everyone that was there for him, to know that was gone. It was just so hard to know. I couldn't even believe that he was actually gone."

DAN WILLIAMS EL PASO, TEXAS "The El Paso community continues to mourn the horrid events over the weekend. This is now one of the worst mass shooting in US history. And tensions continue to run high ahead of President Trump's visit here."

"Don't let him come here. That's what I have been hearing all day."

US Congresswoman Veronica Escobar is among those who say Trump isn't welcome.

VERONICA ESCOBAR TEXAS CONGRESSWOMAN "The words that he has used to describe Hispanics and immigrants have fueled a lot of that hatred and bigotry and have inspired some violence."

Trump will also visit Dayton, Ohio, the scene of the other mass shooting last weekend. There, a small group of protesters showed their feelings about the visit. The mayor of the city has criticized the president for not being stronger on gun control. Mexican authorities are threatening legal action, claiming the U.S. failed to protect their citizens that died in the El Paso attack. Two cities devastated by mass shootings united in grief.
