Former Arkansas Governor Mike Huckabee has lashed out at Mitt Romney after he blasted President Donald Trump for his 'appalling' conduct revealed in the Robert Mueller report. Huckabee retweeted a post where Utah senator Romney said he was 'sickened by the dishonesty' in reference to the investigation into possible collusion with the Russians in the 2016 election, adding that he felt similarly about Romney's running for president in 2012. '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 posted to his 1.27 million Twitter followers on Friday. Former Arkansas Governor Mike Huckabee admitted it makes him sick that Mitt Romney got GOP nomination in 2016 and could have been US President Huckabee tweeted Friday that Romney took Donald Trump's money but still trashed him later Huckabee didn't stop there about Romney who was the 70th governor of Massachusetts from 2003 to 2007. He later added more insult about Romney on the micro-blogging website when he shared an article claiming Trump's reactions to the probe were 'nothing but a president frustrated at being wrong accused and wrongly investigated over a very effective hoax'. Huckabee tagged along to a link to the article: 'There were some Republicans (like Mitt) who really didn't understand what the Mueller report revealed.' Huckabee was a candidate in the Republican presidential primaries in 2016, Trump's election year, and 2008 when Romney also ran. Throughout primaries, he and John McCain accused Romney of flip-flopping with his policies and McCain ultimately succeeded as presidential candidate. McCain had Romney on a shortlist for Vice President but ultimately went with Sarah Palin and they lost to Barack Obama. But Huckabee seemingly denied a tweet saying that Huckabee and Romney were 'bitter rivals'. 'More context-rivals in 08 for sure but in 2012 I campaigned across USA for him, spoke for him at RNC,' Huckabee tweeted Saturday. 'He doesn't have to like @realDonaldTrump as a lot of elitists don't. But we need flip-flops on the beach, not in the Senate.' Huckabee claimed Romney 'begged to be Secretary of State' after Trump won 2016 election.

'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 said in a Twitter statement. 'I am also 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 and that the campaign chairman was actively promoting Russian interests in Ukraine.' Romney, who in 2016 vied with Trump for the Republican presidential nomination, was alone among Republicans in criticizing the White House for its behavior.

The report also detailed numerous acts by the president that supported allegations of obstruction of justice, though Mueller, constrained by Justice Department rules, could not himself recommend charges against Trump. Trump declared victory and exoneration after the report, and later labeled Mueller's work 'total bulls**t.' 'Reading the report is a sobering revelation of how far we have strayed from the aspirations and principles of the founders' of the United States, Romney said. He seemed to be referring to glaring errors that Sarah Sanders, the White House press secretary, made among others. She admitted to the Mueller that she was wrong to say that 'countless' FBI agents told her they wanted James Comey fired. Huckabee denied his reaction came from being 'bitter rivals' as he supported Romney in 2012All rights reserved for this news site dailymail and under his responsibility
