US Defense Secretary Chuck Hagel has been sworn in after a divisive Senate debate over his nomination that signals a rocky road ahead as he tackles deep budget cuts and frayed ties with Congress.
Hagel, 66, took his oath of office at about 8:30 am (1330 GMT) at the Pentagon as his wife looked on, becoming the first combat veteran from the Vietnam conflict to take up the post.
Despite the bitter atmosphere that prevailed at his confirmation hearing, in which the ex-senator was pummeled by his former Republican colleagues over his statements on Israel and Iran, officials said Hagel would focus on the work at hand and seek to cooperate with Congress.

"Senator Hagel has signaled his very strong commitment right away to get down to business, to get deeply invested in the work of the Pentagon and its military and civilian workers," Pentagon spokesman George Little said Tuesday.
"His goal is to look to the future."
After a bruising Senate confirmation hearing and a 10-day delay engineered by Republicans, senators voted 58-41 to approve Hagel for the post previously held by Leon Panetta.
Although his opponents failed in the end to derail his nomination, their hostile stance signaled that Hagel will not be afforded much breathing room when it comes to working with Congress, without the kind of bipartisan support his predecessors enjoyed.
Within 48 hours of being sworn in, Hagel will confront steep automatic budget cuts of roughly $46 billion which are due to kick in Friday due to political deadlock in Congress.
