FILE – In this April 30, 2013, file photo President Barack Obama answers questions during a White House news conference in Washington during which he said his administration's counter-terrorism bureaucracy "did what it was supposed to" in the Boston bombing investigation.

The calls that were fruit of years of cultivating relationships between the U.S. government and American Muslim communities, efforts made to ultimately prevent the very type of attack that occurred in Boston.
