President Barack Obama's approval rating dropped eight percentage points over the past month, to 45%, the president's lowest rating in more than a year and a half, according to a new national poll.

The CNN/ORC International survey released Monday morning comes as the White House has been reacting to controversies over a massive U.S. government surveillance program; the Internal Revenue Service's targeting of tea party and other conservative groups who applied for tax-exempt status; the administration's handling of last September's attack in Benghazi that left the U.S. ambassador to Libya and three other Americans dead; and the Justice Department's secret collection of journalists' phone records as part of a government investigation into classified leaks.



The poll indicates that for the first time in Obama's presidency, half of the public says they don't believe he is honest and trustworthy. And Americans are split on the controversial National Security Agency anti-terrorism program to record metadata on U.S. phone calls, but they support the NSA program that targets records of Internet usage by people in other countries. That doesn't mean they necessarily like what is going on: Just over six in 10 believe that government is so large and powerful that it threatens the rights and freedoms of ordinary Americans.

A slight majority of those questioned in the poll, which was conducted Tuesday through Thursday of last week, disapprove of the actions of the man who leaked sensitive information about the NSA program. A similar number say Edward Snowden, who fled to Hong Kong, should be brought back to the United States and prosecuted.

The president's approval rating stands at 45%, down from 53% in mid-May. And 54% say they disapprove of how Obama's handling his job, up nine points from last month. It's the first time in CNN polling since November 2011 that a majority of Americans have had a negative view of the president.
