Former Maryland Gov. Martin O'Malley (D) on Monday declared that Donald Trump is a "fascist demagogue."
Following Trump's suggestion on Monday afternoon that the US should institute a "total and complete shutdown of Muslims entering the United States" for the time being, the presidential candidate tweeted that Trump had "remove[d] all doubt."
.@realdonaldtrump removes all doubt: he is running for President as a fascist demagogue.

O'Malley, who has lagged behind front-runner Hillary Clinton and Sen. Bernie Sanders (I-Vermont) in primary polls, has repeatedly criticized Trump for his inflammatory remarks about immigration.
"The fact of the matter is, and let's say it in our debate - because you'll never hear this from that immigrant-bashing carnival-barker Donald Trump - the truth of the matter is that net-immigration from Mexico last year was zero," O'Malley said during the Democratic presidential debate last month.
Trump - who has dismissed O'Malley as a "disgusting, little, weak, pathetic baby" - immediately responded in a tweet.
Hillary and Sanders are not doing well, but what is the failed former Mayor of Baltimore doing on that stage? O'Malley is a clown.
