The Trump re-election campaign was on the offensive Monday morning, a day after Attorney General William Barr released a summary of special counsel Robert Mueller's findings on the possible collusion between Russia and the Trump campaign for presidency.

The campaign sent out a memo to a number of television news networks, warning them about the "credibility" of six of the president's more outspoken critics: Sen. Richard Blumenthal (D-Conn.); Rep. Jerry Nadler (D-N.Y.), chair of the House Judiciary Committee; Democratic National Committee Chairman Tom Perez; John Brennan, the former director of the Central Intelligence Agency; Rep. Adam Schiff (D-Calif.), the chair of the House Intelligence Committee; and Rep. Eric Swalwell, (D-Calif.), who represents most of Alameda County.
