(RNN) - Political challenges are a part of being President of the United States, but Ethel Kennedy's is different - she has challenged Barack Obama to dump a bucket of ice water over his head.
On Facebook, Maxwell Kennedy posted a video Monday of his mother, the 86-year-old widow of Robert F. Kennedy, dumping a bucket of ice water over her head (with the help of a grandchild) to benefit the ALS Association as part of the Ice Bucket Challenge.
"Welcome to Cape Cod, President Obama. I nominate you," she said.
The video was recorded at a Kennedy family reunion at Hyannis Port, MA, this past weekend. Obama was vacationing nearby at Martha's Vineyard.
The Ice Bucket Challenge, which brings awareness to ALS, was started by Pete Frates, 29, a former baseball player at Boston College. ?Frates has lived with ALS? (also known as Lou Gehrig's disease) since 2012 and since has lost the ability to speak.
The challenge works this way: someone calls out a friend to donate money and record themselves as they dump a bucket of ice over their head, and post the video to social media. The friend either accepts the challenge or has to donate even more money to the ALS Society.
Social media has exploded with videos of people dumping ice over their heads and challenging friends and loved ones. Even celebrities have gotten in on the act, like actresses Elizabeth Banks and Eliza Dushku.
According to WCVB in Boston, the ALS Association has raised $1.35 million from July 20 to Aug. 11. Last year during that same period the group raised just $22,000.
