Rep. Devin Nunes, R-Tulare, chairman of the House Permanent Select Committee on Intelligence, rejected calls from his fellow Republican for a special prosecutor to investigate purported ties between Russia and members of President Trump’s administration and campaign. Earlier Saturday, Rep. Darrell Issa, R-Vista , the former House Oversight and Government Reform Committee chair, said it would be inappropriate for Attorney General Jeff Sessions, who was involved with the Trump campaign and is a Trump appointee, to investigate the matter.
