Even as his administration has faced intense scrutiny over a trio of controversies, President Obama's approval rating hasn't suffered, according to a new CNN/ORC International poll released Sunday.

Fifty-three percent of Americans said they approve of the job the president is doing, while 45 percent said they disapprove. That's virtually unchanged from an early April survey in which Obama's approval/disapproval split was 51 percent to 47 percent.

The poll is one of the earliest indicators of how Obama's image has been affected during one of the worst weeks of his presidency. As questions about the deadly attack in Benghazi, Libya, revelations that the Internal Revenue Service targeted conservative groups, and  news that the Justice Department secretly obtained journalists' phone records have fueled Republican attacks, the president has been put very much on defense.
