A more aggressive Illinois Gov. JB Pritzker has emerged on the political stump in recent days — both in terms of what he is saying and where he is saying it.The new tone he has struck has led some to believe a presidential run is indeed in the offing.

These Republicans cannot know a moment of peace,” the Illinois governor said in a fiery speech at a Democratic fundraiser.

In comments to reporters Monday, White House Deputy Chief of Staff Stephen Miller slammed Pritzker’s calls for protests. “His comments, if nothing else, could be construed as inciting violence,” Miller said when asked if the Justice Department would “take action” against the governor.
