"It’s a cliché at this point: Donald Trump constantly misleads the public. But just how often does he do this? A new analysis from the Washington Post tries to put a number on Trump’s false and misleading claims. It concludes: 488: The number of false or misleading claims made by the president. That’s an average of 4.9 claims a day. 10: Number of days without a single false claim. (On six of those days, the president golfed at a Trump property.) 4: Number of days with 20 or more false claims. (Feb. 16, Feb. 28, March 20 and April 21.) He made 19 false claims on April 29, his 100th day, though we did not include his interview with “Face the Nation,” since that aired April 30. According to the Post, the misleading or false statements came from just about every venue possible — speeches, interviews, other unscripted remarks in front of reporters, and social media."
