Peter Schweizer's new book Red-Handed: How American Elites Get Rich Helping China Win tells the story of how Sen. Dianne Feinstein's (D-CA) husband Richard Blum was part owner of a Chinese firm that allegedly sold computers with spyware chips to the U.S. military. The military has never been able to calculate how much sensitive data these computers allowed China to steal.

A hefty chapter of Red-Handed is devoted to tracking Feinstein's long and expensive relationship with Communist China. The senator has made herself very, very useful to Beijing — so useful that she actually tried to excuse the Tiananmen Square massacre by suggesting China only called in combat troops to murder thousands of demonstrators because it ran out of cops.

In a total coincidence that could not possibly have been related in any way to Feinstein's friendship with the tyrants of Beijing, her husband did a great deal of lucrative business with Chinese companies, including entities run by the Communist government and linked to the People's Liberation Army (PLA). 

One of those deals saw Blum becoming a major investor in a computer company that was founded by researchers from the Chinese Academy of Sciences (CAS), an institution tied to both the Chinese government and the PLA. The company was originally called Legend, but is better known by its second name, Lenovo.

Lenovo grew into a major player in the worldwide computer marketplace after it acquired IBM's line of personal computer products in 2005. Lenovo's deal to buy IBM's business included $350 million in investments from three American private equity firms. One of them was Richard Blum's Newbridge Capital.

Some lawmakers worried Lenovo's purchase of IBM's personal computer line could jeopardize U.S. national security and transfer advanced American computer technology to China. Sen. Dianne Feinstein, who sat on the Senate Intelligence Committee at the time, was not one of them.
