“There’s no conversation about” firing Mueller “whatsoever in the White House,” Marc Short, the White House legislative director, told NBC’s Chuck Todd. “I read that the president’s own lawyer says” Trump isn’t going to fire Mueller, Sen. John Cornyn (R-Texas) told ABC’s George Stephanopoulos. “I think that would be a mistake myself.” But both men devoted large chunks of their time on the morning shows trying to discredit and undermine Mueller. Cornyn, who challenged the legitimacy of the probe in a tweet Saturday night, criticized Mueller for having an FBI agent on his team who sent text messages critical of Trump. When Stephanopoulos noted that the agent, who also criticized Sen. Bernie Sanders (I-Vt.) and former Attorney General Eric Holder, has already been removed from the investigation, Cornyn doubled down.
