MARC THIESSEN IN THE WASHINGTON POST: Explain the Chinese spy, Sen. Feinstein.

Imagine if it emerged that the Republican chairman of the House or Senate intelligence committee had a Russian spy working on their staff. Think it would cause a political firestorm? Well, this month we learned that Sen. Dianne Feinstein (D-Calif.) had a Chinese spy on her staff who worked for her for about 20 years, was listed as an “office director” on payroll records and served as her driver when she was in San Francisco, all while reporting to China’s Ministry of State Security through China’s San Francisco Consulate. The reaction of the mainstream media? Barely a peep.

Just think of the media as Democratic Party operatives with bylines, and the silence makes perfect sense.
