John Kasich makes wild claim about President Trump after Mueller report

Former Ohio Gov. John Kasich (R) over the weekend reacted sharply to the public release of special counsel Robert Mueller's report on the investigation into Russian interference and the Trump campaign, slamming President Donald Trump for "unacceptable" behavior.

What did Kasich say?

Trump's actions outlined in Mueller's report, which included outright lies and attempted investigative manipulation, are the worst Kasich has ever witnessed in his political career, he said.

".@realDonaldTrump's behavior described in the #MuellerReport is more than disappointing. It's unacceptable & not behavior we should expect from our president. It's worse than I've seen in my career observing & working with presidents or public officials. America deserves better," Kasich wrote on Twitter.

Kasich has been actively involved in national politics for more than three decades, spanning the scandals of Bill Clinton's administration and the scandals of Barack Obama's administration, which included Hillary Clinton's private email server debacle.

Presumably, Kasich believes Trump's actions are worse than the scandals that marred previous Democratic presidential administrations.

Later, Kasich posted comments he made on CNN in which he explained the Mueller report puts on public display the exact reasons why he never supported Trump.

"I'm not only disappointed and angry — I'm sickened by all this," Kasich said.

Kasich's comments came one day after another prominent Republican, Sen. Mitt Romney (R-Utah), blasted Trump for his actions as outlined in Mueller's report. Trump later responded to Romney's comments with a viral video online.

Kasich finished second to Trump in the 2016 Republican presidential primary.
