Sarah Palin gets White House address wrong

Sarah Palin has made another public blunder by getting the address of the White House wrong.

The former Republican vice-presidential nominee said the President Obama's residence was located at "1400 Pennsylvania Avenue".

It is actually located at 1600 Pennsylvania Avenue.

Palin made light of her mistake on Twitter - but her joke contained a grammatical error.

She later sent a picture of herself at the wrong address to CNN reporter Jake Tapper.

During her speech at the Values Voter Summit in Washington, Palin also joined the criticism of President Obama for his "coffee cup" salute last week.

"'To the commander -in-chief, we then salute him," she said before sarcastically waving a cup.
