Actor Dean Cain slammed longtime Trump critic Rosie O'Donnell on Friday for suggesting the United States military remove the president from the White House.

O'Donnell made the remark Thursday on MSNBC, during a segment where Trump's threat to have the military close southern border was discussed.

The president tweeted that he will "call up the U.S. Military" if Mexican officials don't stop the northern progress of a migrant caravan.

"I want to send the military to the White House to get him," O'Donnell said.

Cain said on Tucker Carlson Tonight that O'Donnell's comments were a "thinly veiled" joke but that, like her call to impose martial law in order to delay Trump's inauguration last January, it was "insane."

"Even on [MSNBC], all they did was laugh. ... Why didn't anybody offer a dissenting opinion and say, 'That doesn't make any sense?'" he said.

O'Donnell added on Thursday that she "took a year out of the spotlight" after Trump was elected to compose herself.
