Washington (CNN) George Conway, a conservative lawyer and the husband of White House counselor Kellyanne Conway, argued in a new op-ed that President Donald Trump is unfit for office, regardless of the Mueller report's findings.

"If the charge were unfitness for office, the verdict would already be in: guilty beyond a reasonable doubt," Conway wrote in a Washington Post op-ed published Tuesday.

Special counsel Robert Mueller did not find that Trump's campaign or associates conspired with Russia, according to Attorney General William Barr's summary of the report submitted to Congress on Sunday. Mueller's investigation of whether the President committed obstruction of justice did not conclude the President committed a crime, but it also "does not exonerate him," Barr wrote, quoting from Mueller's report.

Mueller did not make the decision himself on whether to prosecute the President on obstruction. Barr and Deputy Attorney General Rod Rosenstein made the determination the evidence was "not sufficient" to support prosecution.

"If his report doesn't exonerate the president, there must be something pretty damning in it about him, even if it might not suffice to prove a crime beyond a reasonable doubt," George Conway suggested.
