On the March 21 broadcast of ABC's World News, anchor Charles Gibson corrected chief investigative reporter Brian Ross' March 19 assertion -- noted by Media Matters for America -- that Sen. John McCain had released his tax returns.

From the March 21 broadcast of ABC's World News with Charles Gibson:

GIBSON: We have a correction to make: On Wednesday, in a story about the release of Hillary Clinton's White House schedule as first lady, we reported that she, unlike Senators Obama and McCain, has not released her tax returns. In fact, only Obama has released his tax returns. Both Senators Clinton and McCain say they will release theirs next month.
