Red Lines! President Trump's frustration with the Russia probe boiled over in a fiery new interview where he set a red line for Special Counsel Robert Mueller, warning against digging into his family finances beyond the Russia scope and suggesting he'll soon start talking about the ex-FBI director's "conflicts." The president has regularly complained about the Russia meddling probe, before and after it was placed in the hands of the special counsel. But his comments to The New York Times indicate he's preparing to get even more aggressive in challenging the credibility of the investigation. Significantly, he said Mueller would cross a red line if he started looking at Trump family finances going beyond any Russia connection. ''I think that's a violation. Look, this is about Russia," Trump said.
