Obama warns divided Congress that he will act alone

WASHINGTON (Reuters) - President Barack Obama vowed on Tuesday to bypass a divided Congress and take action on his own to bolster America's middle class in a State of the Union address that he used to try to breathe new life into his second term after a troubled year.

Standing in the House of Representatives chamber before lawmakers, Supreme Court justices and VIP guests, Obama declared his independence from Congress by unveiling a series of executive orders and decisions - moves likely to inflame already tense relations between the Democratic president and Republicans.
