Steyer launched a multimillion-dollar ad campaign slamming Trump’s actions on health care, immigration and the environment. The campaign included a television ad that ran during “Fox and Friends,” a show the president is known to watch often.

Trump responded to Steyer’s calls for impeachment on Twitter, calling him “wacky” and “unhinged.”
