After 100 days in office, Trump says the media aren't reporting his achievements.

US President Donald Trump has celebrated his first 100 days in the White House with cheering supporters at a campaign-style rally, touting his initial achievements and lashing out at critics who have given his tenure poor marks.

Trump told a Pennsylvania crowd on Saturday night he was just getting started on meeting his campaign promises. He repeatedly attacked an “incompetent, dishonest” media, saying they were not telling the truth about his administration’s accomplishments.

Mainstream (FAKE) media refuses to state our long list of achievements, including 28 legislative signings, strong borders & great optimism!

“My administration has been delivering every single day for the great citizens of our country,” Trump said in Harrisburg, Pennsylvania. “We are keeping one promise after another, and frankly the people are really happy about it.”

The rally occurred on the same day as a climate march at which thousands of protesters surrounded the White House, and it also coincided with the annual black-tie White House press dinner in Washington. Trump and his staff chose to skip the press dinner because of what he said was unfair treatment by the press.

Trump said he was thrilled to be away from the “Washington swamp”.

“A large group of Hollywood actors and Washington media are consoling each other in a hotel ballroom in our nation’s capital right now,” Trump said to loud boos from the crowd.

“If the media’s job is to be honest and to tell the truth, the media deserves a very, very big fat failing grade.”
