Maxine Waters says Trump is capable of starting a civil war

During today's debates about impeaching President Donald Trump for the second time, Rep. Maxine Waters claimed that President Trump was "capable of starting a civil war." Parts of her speech went like this (not all of it is here, just some of the main points):

“I rise in support of impeaching again, the worst president in the history of the United States.

This president has spent four years abusing his power, lying, embracing authoritarianism [and] radicalizing his supporters against democracy. This corruption poisoned the minds of his supporters, inciting them to willingly join white supremacists, neo-Nazis and paramilitary extremists in a siege of the United State Capitol building, the very seat of American democracy... This president intends to exercise power long after he is out of office … we should be concerned that the Republicans will not defend him and he is capable of starting a civil war. He must be impeached. He must be stopped now."
