Watergate journalist Bob Woodward claimed Wednesday night that a White House
aide sent him an email saying he would "regret" his comments. The aide was not identified, but an official familiar
with the exchange told Fox News it was National Economic Council Director Gene Sperling. That was after Woodward wrote a column
this past weekend claiming Obama was trying to re-write history -- regarding not only whose idea the sequester was, but also
how it would take effect.
