Chris Christie To Endorse Romney

Mitt Romney will score another major endorsement Tuesday afternoon when New Jersey Gov Chris Christie will announce he is backing the former Massachusetts Governor's White House run.

The announcement will take place in Hanover, New Hampshire, just hours before the latest GOP presidential debate takes place at Dartmouth University.

The plain-spoken Christie has become a darling of establishment Republicans by slashing spending and fighting unions in New Jersey and was repeatedly urged to make a presidential run of his own for months.

This is another key endorsement for Romney who also won the backing of former Minnesota Gov Tim Pawlenty shortly after he dropped out of the presidential race.
