George Conway Congratulates Trump on Surpassing 10,000 False Claims: 'No One but You Could Have Achieved This'

George Conway has congratulated President Donald Trump on surpassing 10,000 false claims.

Branding the POTUS "Deranged Donald", Conway joked on Twitter that the milestone was something only Trump could have achieved.

"An amazing accomplishment!" Conway, whose wife Keyllanne Conway is the president's counselor, tweeted on Monday.

"No one but you could have achieved this. Not just the number. Covering all topics, never shying from even the most brazen, disprovable lies, you've even managed to tell multiple lies on same subject, lying even about lying!!"

Conway's latest dig at trump came after The Washington Post tweeted the number of false or misleading claims recorded by its Fact Checker database, which checks the veracity of statements made by Trump, had ticked over 10,000.

According to the Post, the president reached the unwanted milestone on April 26, racking up some 171 false or misleading claims just by virtue of a series of tweets he fired out over a three-day period beginning on April 25.

Data compiled by the Fact Checker shows around 20 percent of Trump's misleading claims are about immigration issues, with the construction of the wall along the border with Mexico a particular favorite of his.

The president has claimed that the wall is being built on 160 different occasions, despite the fact the Congress' refusal to meet his financial demands caused the longest government shutdown in U.S. history between December and January.

The issue of the border wall is not the only one that features prominently in the Fact Checker. In fact, there have been at least 300 instances in which Trump has repeated the same claim one way or the other at least three times.

According to the Post, it has taken Trump less than a year to move from 5,000 false claims to twice as many. That means that over the last seven months Trump has averaged 23 false or misleading claims per day.

By comparison, it took him 601 days to rack up his first 5,000 false or misleading claims of his presidency, at a rate of approximately eight per day.

The average was even lower during Trump's first 100 days at the White House, when he reportedly averaged less than five claims a day. Had he kept up the average, he would have totaled 7,000 misleading claims over his first four years at 1600 Pennsylvania Avenue.

Conway first wheeled out the hashtag "Deranged Donald" last week, when he shared a report from The Washington Post that debunked Trump's claim Britain helped the Obama administration in spying on his campaign during the 2016 presidential election.

The President's comments were based on a report attributed to conservative One America News Network, in which former CIA analyst Larry Johnson suggested without evidence Britain had been involved in spying.
