"The very first thing the president did was condemn the (synagogue) attacker and the very first thing the media did was blame the president", White House Press Secretary Sarah Sanders told reporters on Monday when asked Trump's comments in wake of the shooting.
Acosta continued to press her, asking, "If you're going to stand there and continue to say that there are some journalists, some news outlets in this country that meet that characterization, shouldn't you have the guts, Sarah, to state which outlets, which journalists are the enemy of the people?"
"The president wants to be there (Pittsburgh) to show the support of this administration", Sanders said, noting that the synagogue's spiritual leader, Rabbi Jeffrey Myers, has said he would accept a visit from the president.
"The very first thing the media does was blame the president".
"President Trump, you are not welcome in Pittsburgh until you fully denounce white nationalism", Bend the Arc, a Jewish social justice organisation, said in an open letter to Trump, who announced he will visit the city tomorrow. "At times, I think there's individuals that the President would be referencing".
Trump said Saturday after the shooting that there is no need for stricter gun laws, instead telling reporters before traveling to a campaign rally in IL that he believes the religious facility should have had armed guards.
Acosta asked Sanders which outlets she and Trump regard as enemies of the American people.
Trump will travel to Pennsylvania on Tuesday with first lady Melania Trump.
Police say the shooter told them he hated Jews because they were "committing genocide to his people".
Trump has made fear of the migrant caravan a key talking point in his raucous election rallies where he accuses Democratic opponents of seeking to let in "rapists" and "vicious" criminals.
The group said Jews are not the only ones who have been targeted by Trump's rhetoric; the president has "deliberately undermined the safety of people of colour, Muslims, LGBTQ people, and people with disabilities", it said.
President Donald Trump clarified his stance as to what media he regards to be "enemy of the people" - but the clarification differs negligibly from the commonly reported definition. "And they were the religious heart of the Tree of Life community", Sanders said. "Blowback from his words came and cost people's lives, and we said enough is enough". Such rhetoric encouraged right-wing extremism, Trump's critics say, an accusation that the administration has flatly rejected.
Federal prosecutors are considering seeking the death penalty against the suspect.
"I think the president has had a number of moments of bringing the country together", she said.
