Fox Business host Lou Dobbs got into a heated exchange with former Trump spy chief Richard Grenell about the Trump campaign’s legal efforts to defend the president’s road to electoral victory.

During an interview Thursday afternoon, Dobbs asked Grenell about taking legal action in Nevada as the margin between the candidates continues to narrow. Grenell claimed approximately 3,060 people illegally voted in Nevada because they didn’t meet the residency requirement. “This is easily available information that the media should’ve found. We found it today. We are releasing this,” Grenell said.
