Just 48 hours after the U.S. President signed agreements with Russian president Dmitry Medvedev to reduce weapon stores, 11-year-old Malia Obama was spotted wearing not one, but two T-shirts with an anti-nuclear message.
She wore the tops emblazoned with the Campaign for Nuclear Disarmament's famous logo as her father prepared for three days of G8 talks in Italy.
The symbol, designed for the CND in 1958, is now widely used to signify peace and is also an international sign for anti-war protesters.
Mr Obama spent two days in Moscow this week meeting president Dmitry Medvedev and prime minister and former president Vladimir Putin.
There the American and Russian leaders agreed a landmark deal to reduce their stockpiles of nuclear weapons.
Malia is apparently a fan of her father's work, though the deal is simply a 'guide' for negotiators as the nations work toward a replacement pact for the START arms control agreement, which expires in December.
The CND, a British campaign, aims to rid the world of nuclear weapons and weapons of mass destruction.
In April, Mr Obama made a speech in Prague committing to nuclear disarmament which was 'warmly welcomed' by the CND.
It has also welcomed this week's agreement between Russia and the U.S., claiming the 'first step has been taken' in abolishing nuclear weapons.
Mr Obama's family are accompanying him at the G8 summit in the Italian town of L'Aquila for three days of talks on global issues such as climate change, trade and financial reform with Britain, Canada, France, Germany, Italy, Japan,and Russia.
