Should Donald Trump make good on his threats to sue media organizations and critics whom he believes have disparaged him, he will end up "looking like the fool that he is."

That is the opinion of conservative lawyer and Trump critic George Conway during an appearance on MSNBC on Sunday morning.

Speaking with the hosts of "The Weekend," Conway said the president-elect's threat to use the courts to go after his critics has no basis in law and are solely designed as vehicles of harassment and attempts to silence criticism.

Using Trump's threat to sue Iowa pollster Ann Selzer for "election interference" as an example, Conway explained, "It's the laws. You have to have laws that are violated to bring these actions whether they be brought in his personal capacity or by the government. This is all nonsense."

"Especially suing the pollster?" he continued. " There is no claim for suing a pollster, putting out a poll that doesn't predict the right result. And think about this: he is saying they lied about a poll. There is no person on this planet who has lied more about polls than Donald Trump. I mean, he is always saying he is ahead, he is never behind in the polls."
