The election season violence rattled a deeply divided nation and prompted questions about whether Trump should tone done his rhetoric.
Monday's briefing comes at a fraught time for Trump, who is facing criticism over his heated political attacks in the wake of last week's bomb scare involving prominent Democrats and a mass shooting on Saturday at a Pittsburgh synagogue.
White House spokeswoman Sarah Huckabee Sanders said Monday that Trump will go "to express the support of the American people and to grieve with the Pittsburgh community".
Such briefings were once a fixture of the White House's daily schedule, but they have largely disappeared in recent months as President TrumpDonald John TrumpPittsburgh mayor: Our priority is funerals not Trump's visit Trump says he will respond to "some" of Mueller's questions Trump: "Dishonest" to say I called all media "enemy of the people" MORE has chose to take his communications strategy into his own hands.
He said the media "must stop the open & obvious hostility & report the news accurately & fairly".

In the same report, the New Jersey spokeswoman Nicole Kirgan said children are particularly at risk with this virus. Most adenovirus infections are mild, with symptoms usually lasting about 10 days, according to the CDC .
The White House has pushed back against the suggestion Trump should change course.
The White House announced the trip Monday amid a mounting row over whether Trump's fierce rhetoric at campaign rallies and on Twitter has been partly responsible for stoking extremist fires ahead of November 6 midterm elections. "Wrong! I said that the "Fake News (Media) is the Enemy of the People", a very big difference", he tweeted.
Leaders of a liberal Jewish group in Pittsburgh penned an open letter to the president, saying he was not welcome until he denounced white nationalism.
But Rabbi Jeffrey Myers of the Tree of Life synagogue made clear Trump would be welcome, telling CNN: "The President of the United States is always welcome". I'm a citizen. He's my president.
Sanders told reporters that people should place the responsibility for the two attacks on the individuals responsible.

Earlier, the pair expressed their admiration for mental health workers at a beachside morning tea in Wellington . Recalling a discussion she had with Meghan, Jessina Oakes, 26, said: "She said a really handsome quote".
"If the President is looking to come to Pittsburgh, I would ask that he not do so while we are burying the dead".
The White House did not immediately respond to the mayor's request.
"That is outrageous", said Sanders. "She has admitted it's a smear (only some of them are enemies!), and yet she propagates an accusation that influenced a bombing attempt against a news outlet and is used as justification for violence against journalists around the world". Not just on the president, but everybody that works in this administration.
"The president is trying to heal the country", she said.
Throughout his campaign and presidency, Trump has been an unrelenting critic of the media. Last week, the NY offices of CNN, the cable network frequently criticized by Trump and his supporters, was evacuated after receiving an explosive device and an envelope containing white powder.

The Beijing based company Landspace developed a carrier rocket to take satellites up to space to orbit the earth. Recall that in 2018, China plans to launch 40 rockets, including his most powerful at the moment, Changzheng-5.
A presidential visit to the site of a tragedy is not necessarily unusual but in the increasingly febrile atmosphere ahead of the midterms - where opposition Democrats hope to take control of at least one house of Congress - Trump's trip is mired in politics. He is planning an aggressive campaign schedule during the final days leading up to the November 6 elections. "I refer to Fake News Media when mentioning Enemy of the People - but dishonest reporters use only the word 'Media.'", he said. On Twitter on Sunday, he savaged billionaire businessman Tom Steyer, another target of the mail bombs, as a "crazed & stumbling lunatic".
