Pussy Riot: Power to join them? Russia wants to know.

U.S. Ambassador to the United Nations Samantha Power on Wednesday discussed "disturbing" trends in Russia with previously jailed members of the Russian punk band Pussy Riot, prompting Moscow's U.N. envoy to ask if she was joining the group.

Power, who was well known for her own human rights activism before she joined the first administration of U.S. President Barack Obama after his 2008 election, met at the U.S. mission to the U.N. with Nadezhda Tolokonnikova and Maria Alyokhina ahead of their appearance at an all-star concert.

Power and the two band members discussed "the disturbing trend in (Russia) of legislation, prosecutions and government actions aimed at suppressing dissent and pressuring groups that advocate for fundamental human rights and basic government accountability," Power's deputy spokesman Kurtis Cooper said.

The case of Pussy Riot sparked a global outcry. In 2012 Tolokonnikova, 24, and Alyokhina, 25, were convicted of hooliganism motivated by religious hatred after storming Moscow's biggest Orthodox cathedral and beseeching the Virgin Mary to rid Russia of President Vladimir Putin.

Russian U.N. Ambassador Vitaly Churkin was asked about Power's roughly half-hour meeting with the two Pussy Riot members during a briefing at the Russia mission.

"She has not joined the band?" he asked. "I would expect her to invite them to perform at the National Cathedral in Washington. This is my expectation."

"Maybe they could arrange a world tour for them, you know," he said. "St Peter's Cathedral in Rome, then maybe in Mecca in Saudi Arabia, ending up with a gala concert at the Wailing Wall in Jerusalem. So if Ambassador Power fell short I would be disappointed."

Russia's leadership has not attempted to hide its annoyance when Washington criticizes Moscow for its human rights record. The Russian Federation has in turn accused the United States of rights abuses at home.
