(CNN) Security breaches at the White House are not uncommon. Two happened in the past eight days -- on Saturday when a person jumped a bike rack in front of the executive residence, and March 10, when a man carrying a letter for President Donald Trump was arrested near the south entrance.

Past cases range from the seemingly benign to extremely dangerous.

Here are six other incidents when security was penetrated at the White House. Neither the president nor his family were injured in any of these incidents.
