Were they trying to swerve and protect? Two senior agents are under scrutiny after allegedly disrupting an active bomb investigation and ramming a government-issued car — possibly while drunk — into a White House barricade on March 4. The men actually drove by the suspicious package, sources said. It’s the latest black mark on the beleaguered agency and the first scandal under new chief Joseph Clancy, who faces pressure from Congress to provide a full accounting of the incident. At his appointment, Clancy promised to restore America’s trust in the men and women charged with protecting the president.
