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.

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.

Illinois Gov. JB Pritzker on Sunday took a stage commanded by past presidential hopefuls and implored Democrats to forcefully resist the Trump administration, while panning leaders in his own party for acting too timid for too long.
