HARRISBURG, Pa. - US President Donald Trump hit the road on Saturday to celebrate 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 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."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."Trump listed what he said were some of his key early accomplishments, including the successful confirmation to the US Supreme Court of Justice Neil Gorsuch and clearing away many regulations on the environment and business.He also listed his approval of the Keystone XL and Dakota Access pipelines, killing a pending Asian trade pact, and enhanced security measures that have led to a sharp decline in illegal border crossings at the southern border."The world is getting the message: if you try to illegally enter the United States, you will be caught, detained, deported or put in prison," Trump said.He shrugged off his failure to score major legislative victories on his core campaign promises, such as repeal and replacement of the Affordable Care Act and construction of a Mexican border wall. Trump's ban on visitors from some Muslim nations was blocked in court.He blamed Democrats for the legislative failures so far and said all of his promises would be kept eventually."We'll build the wall people, don't even worry about it," he said.Trump said he reversed course on promises to name China a currency manipulator because he wanted China's help in trying to rein in North Korea's nuclear and missile development. Trump has said all options are on the table if Pyongyang persists in its nuclear development.Trump left Washington as another in a series of protests against his administration was winding up. Thousands of marchers made their way through Washington's streets during the People's Climate March, a protest against Trump's moves to roll back environmental regulations.Asked by reporters accompanying him to Pennsylvania what he had to say to the climate change protesters, Trump said: "Enjoy the day, enjoy the weather."
