Bruce Fredrich, the PETA spokesman said, "We support compassion even for the most curious, smallest and least sympathetic animals. We believe that people, where they can be compassionate, should be, for all animals," he added.
It was during an interview for CNBC at the White House on Tuesday, Jun 16 that Obama killed a fly, which had intruded on his conversation with correspondent John Harwood.
Friedrich said that PETA was pleased with Obama's voting record in the Senate on behalf of animal rights, and with the fact that he has been outspoken against animal abuses.
"(Still) swatting a fly on TV indicates he's not perfect, and we're happy to say that we wish he hadn't," Friedrich added.
Deputy press secretary Josh Earnest said the White House had no comment on the matter.
