Pollster John Zogby reports in our weekly White House report card that the internet tapping scandal has stalled the president's agenda and hit his approval ratings.

"Summer is here and it is time for scandals in Washington. And there are some doozies. Despite President Obama's efforts to finesse the issue and tell Americans they have nothing to worry about, the National Security Agency invasion of privacy issue is in the forefront, stalling the president's agenda. Polling shows that Americans are willing to trade off privacy for security, but it also shows that Obama's approval ratings are sliding a bit to the mid-40 percent level. I am willing to admit that my polling still shows the president at 52 percent approval and is the outlier. But he is back up to waist deep in scandal."

This week's grade: D
