In late 2003, after three years as a high-level saleswoman, Christina Elwell says she had so impressed her bosses at Internet search giant Google Inc. that she was promoted to national sales director...But all that changed, according to a lawsuit filed against the company in federal court in Manhattan last week, after Elwell told her boss several months later she was pregnant with quadruplets and experiencing medical complications...Google spokesman Steve Langdon said, "The lawsuit against Google and Tim Armstrong is without merit and we will defend vigorously against it."
