White House counselor Kellyanne Conway’s husband hopped on Twitter — again — to slam President Donald Trump, this time blasting his “ceaseless, shameless, witless prevarication on virtually all topics.”

George Conway issued the tweet in response to Trump’s own tweet Friday complaining about former President Barack Obama mistakenly saying — a decade ago — that he had visited 57 states during 15 months of campaigning. Obama later indicated to reporters that he might have been getting a bit tired. The fact-checking Snopes website deemed it a “slip of the tongue.”

Trump complained that there was “very little mention” of Obama’s blooper in the “fake news media,” adding: “Can you imagine if I said that ... story of the year.”

That’s when Conway, a conservative lawyer, decided to point out the differences between the credibility of the two presidents:

Needless to say, there’s a huge difference between an isolated slip of the tongue and ceaseless, shameless, and witless prevarication on virtually all topics, large and small. https://t.co/mvV8cgZLyp — George Conway (@gtconway3d) September 15, 2018

Conway has issued a slew of tweets zapping the president after Trump took office. He has most recently been retweeting links to stories about Trump’s low approval ratings and the president’s former campaign manager Paul Manafort reaching a cooperation plea deal with special counsel Robert Mueller

A Washington Post feature last month about the couple quoted Kellyanne Conway as saying that her husband’s tweets were “disrespectful” and “a violation of basic decency, certainly, if not marital vows.” She demanded that she be quoted as an anonymous source, but the newspaper refused.
