Barbara Walters following a 2012 interview with Pres. and Mrs. Obama.

ABC’s Barbara Walters, in Washington for coverage of the Inauguration, fell on a stair while visiting the British Ambassador’s residence last evening. The fall left her with a cut on her forehead. “Out of an abundance of caution, she went to the hospital to have her cut tended to, have a full examination and remains there for observation,” says ABC News spokesperson Jeffrey Schneider. “Barbara is alert (and telling everyone what to do), which we all take as a very positive sign,” he adds.

Politico’s Mike Allen was first to report the story this morning. Walters, 83, will not be able to contribute to ABC’s reporting tomorrow and may not be back on the air for several days.
