The Russians tipped us off about the older bombing suspect not once, but twice.
A FBI led joint terrorism task force in Boston was alerted about Tamerlan Tsarnaev in early 2011.
Months later, officials in Russia contacted CIA and made a second, identical plea.
The White House said today that federal agents thoroughly investigated the elder Tsarnaev and found no cause for concern.
It’s not known if either alert from Russia could have prevented the bombing in Boston.
