President Trump took broad aim at “Never Trumper” Republicans in a Wednesday afternoon tweet, calling the dissenting members of the GOP “human scum.”

The president condemned the Never Trump movement as he was headed to a conference in Pittsburgh on Wednesday. “The Never Trumper Republicans, though on respirators with not many left, are in certain ways worse and more dangerous for our Country than the Do Nothing Democrats,” he tweeted. “Watch out for them, they are human scum!”
