US President Donald Trump has visited the Ohio city that suffered one of last weekend's two deadly mass shootings as critics accused him of inflaming tensions with anti-immigrant rhetoric.
Trump visited survivors, first responders and staff at Miami Valley Hospital in Dayton, Ohio, where nine people and the gunman were killed in a rampage early on Sunday.
- Ohio shooting: Nine killed by gunman in Dayton, Ohio
- Dozens dead after two mass shootings in the US
- El Paso shooting: Twenty killed after gunman opens fire in Walmart
Dozens of protesters outside the hospital set up a "baby Trump" blimp balloon and held signs reading "Do Something" "Save our city" and "You are why".
Later on Wednesday Trump will visit the Texas city of El Paso, on the border with Mexico, where 22 people were killed at a Walmart store on Saturday by a 21-year-old man who had posted an anti-immigrant manifesto online.
The back-to-back massacres - 13 hours apart - have reopened the national debate over gun safety and led protesters in Dayton to heckle Ohio's Republican governor Mike DeWine at a vigil for the shooting victims with chants of "Do something".
As he left the White House, Trump said he wanted to strengthen background checks for gun purchases and make sure mentally ill people did not carry guns.
He predicted congressional support for those two measures but not for banning assault rifles.
"I can tell you that there is no political appetite for that at this moment," Trump told reporters at the White House.
"But I will certainly bring that up ... there is a great appetite, and I mean a very strong appetite, for background checks."
In Dayton, Trump was greeted at the airport by a bipartisan group of state and local officials, including Democratic Dayton Mayor Nan Whaley.
Whaley has said she would welcome Trump but planned to tell him he had been "unhelpful" on the issue of gun violence.
Critics have said Trump stokes violence with racially incendiary rhetoric. The El Paso massacre is being investigated as a hate crime and the FBI said the Dayton shooter had explored violent ideologies.
On Monday Trump gave a speech focusing on mental health reforms, tighter internet regulation and wider use of the death penalty.
Democrats accuse Trump of hiding behind talk of mental illness and the influence of social media rather than committing to laws they insist are needed to restrict gun ownership and the types of weapons that are legal.
Democratic presidential front-runner Joe Biden planned to say in a campaign speech in Iowa that the US has a President with "a toxic tongue" who has embraced a political strategy of hate, racism, and division.
In a sign of higher tensions after the shootings, a motorcycle backfiring on Tuesday night in New York's Times Square sent crowds running for fear of another gun attack.
"People are obviously very frightened," New York Governor Andrew Cuomo told CNN.
Authorities in Texas have said they are investigating Saturday's shooting spree in the predominantly Hispanic city of El Paso as a hate crime and an act of domestic terrorism.
They cited a racist manifesto posted online shortly before the shooting, which they attributed to the suspect.
