Here's Spektor's reaction, from a longer article on Spinner.Com by Michael B. Ayers.
"Having moved to America from Soviet Russia as a child with my family, we dreamed of reconnecting with our religious traditions and of making America our home" Spektor said in a statement. "Having lived here for over 20 years, it is an unimaginable honor to be invited to the White House by President Barack Obama and First Lady Michelle Obama, to an event celebrating Jewish Americans, and to be counted among them. Nothing in the world could make us feel more accepted and at home!"
