"This is simply put, been one of the worst polling weeks for Donald Trump that we've seen. Awful, awful, awful," CNN's pollster Harry Enten said.

President Trump's approval ratings have shifted following a weekend of protests coinciding with a military parade held on his birthday. An estimated 5 million protested across the nation against the president and his administration.

Among Republicans, 89% approve of the second term in office, compared to eight percent of Democrats and 35% of Independents.
