Trump flew to El Paso, Texas, where a self-declared white supremacist murdered 22 people last weekend at a Walmart heavily frequented by customers of Hispanic origin. Also, according to the Washington Post, a number of survivors wouldn't meet with Trump, which isn't surprising.
In the hospital clip, which was shot by a bystander and aired on KFOX14 television, a jovial Trump is seen praising medical staff at the hospital, telling them "they're talking about you all over the world".
Trump is visiting Dayton, where nine people were gunned down by a man whose motives remain unclear, as well as El Paso, Texas, where the shooter had specifically targeted Hispanics, killing 23 people including Mexican nationals.
Trump then tweeted photos from his so-called "rock star" reception at the OH hospital.
Democratic Congresswoman Veronica Escobar and Democratic presidential candidate Beto O'Rourke, who are both from El Paso, have criticised Trump in the aftermath of the shooting.
"A lot of people try and say, 'Look at the good he's done here, bringing money and jobs, ' but I believe our generation is more focused on morals and not money", said 21-year-old college student Victoria Perches told Buzzfeed.
"I will again be spending time with fellow El Pasoans who are dealing with the pain and horror left in the wake of this act of domestic terrorism fueled by hate and racism", she said.
'The love, respect & enthusiasm were there for all to see.
Trump noted that the Dayton gunman's social media accounts showed Connor Betts had left-wing political views, supporting Democratic presidential contenders Bernie Sanders and Elizabeth Warren, and Antifa, anti-fascist protesters. They all blamed him and I want to name and shame them now because he did not respond in kind.
Chanting crowds in Dayton urged Trump: "Do something!"
"I spoke with Attorney General Bill Barr at length; I spoke to Christopher Wray, Director of the Federal Bureau of Investigation; I spoke to the governors - both governors - and we're doing a lot of work".
Ms Escobar is not the only one to suggest Mr Trump faces a cool reception in El Paso. There were supporters of the US President, as well.
Former Vice President Joe Biden, the 2020 Democratic primary frontrunner, made another gaffe Thursday when he told a crowd in Iowa that "poor kids are just as bright and talented as white kids".
The first thing Trump did after leaving Dayton on his way to El Paso was to attack the city's leaders.
Where Trump and his mostly leftist opponents agree is on the unambiguous designation of the two events as terrorism.
"Nothing to do with Trump but nobody ever mentions that", he said.
Mayor Whaley said she agreed with Mr Trump's decision not to visit the district where the shooting occurred, given the high emotions in the community. But he added that while he favored background checks for purchases of such weapons, there was "no political appetite" for an assault weapons ban.
