"I refer to Fake News Media when mentioning Enemy of the People - but dishonest reporters use only the word 'Media.' The people of our Great Country are angry and disillusioned at receiving so much Fake News".
The president's comments follow a mass shooting at a Pittsburgh synagogue and a mail bomb scare targeting senior Democrats and CNN.
President Donald Trump and his wife Melania will travel to Pittsburgh on Tuesday to support the city after 11 people were shot dead in the worst anti-Semitic attack in recent United States history. The election season violence rattled a deeply divided nation and prompted questions about whether Trump should tone done his rhetoric.
While Trump has condemned the Pennsylvania shootings as an anti-Semitic act and has decried political violence, he also has continued his political schedule over the past week and largely kept up his criticism against Democrats and the media.
However, Jeffrey Myers, a Tree of Life rabbi who was in the synagogue when the heavily armed gunman burst in on worshippers, said Trump would be welcome if he visited.
Trump had initially called for unity in the face of Saturday's assault on the Tree of Life synagogue in Pittsburgh, in a week in which prominent Democrats were the targets of pipe bombs sent through the mail, allegedly by a Trump supporter in Florida.
The White House has rejected suggestions Mr Trump should change course.
CNN and others in the Fake News Business keep purposely and inaccurately reporting that I said the "Media is the Enemy of the People". Sanders said Trump would go "to express the support of the American people and to grieve with the Pittsburgh community".
"The president's not trying to reach his base by denouncing anti-Semitism and asking everybody to rise above hate, he's being the president of all Americans", Conway said. He is planning an aggressive campaign schedule during the final days leading up to the November 6 elections.
The president during a Monday night interview with Fox News's Laura Ingraham continued to deride specific media outlets, calling out NBC's "Meet the Press" and The Washington Post. 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 very first thing the media did was blame the president and make him responsible for these ridiculous attacks".
