Former Arkansas Gov. Mike Huckabee lashed out at Sen. Mitt Romney after the Utah Republican said he was “sickened” by the level of dishonesty from President Trump’s administration in response to Special Counsel Robert Mueller’s redacted report into Russian interference in the 2016 election.

“Know what makes me sick, Mitt? Not how disingenuous you were to take @realDonaldTrump $$ and then 4 yrs later jealously trash him & then love him again when you begged to be Sec of State, but makes me sick that you got GOP nomination and could have been @POTUS," Huckabee tweeted Friday.

Earlier in the day, Romney tweeted that it was good news that there was insufficient evidence to charge Trump with collusion or obstruction of justice. The former GOP 2012 presidential candidate then blasted Trump and his campaign for having contacts with Russians.

"I am sickened at the extent and pervasiveness of dishonesty and misdirection by individuals in the highest office of the land, including the President," Romney posted.

"I am appalled that, among other things, fellow citizens working in a campaign for president welcomed help from Russia — including information that had been illegally obtained; that none of them acted to inform American law enforcement," he wrote.

Mueller's long-awaited report was released Thursday morning and contains nearly 900 redactions. It showed investigators found no evidence of collusion between the Trump campaign and Russia. No conclusion was reached on whether Trump’s actions amounted to obstruction.
