Great question. Although I think she means false statements to FBI (Clinton), false statements to Congress (Clapper, Comey).

Sarah Sanders asks the correct question after Stone's indictment:

When will the FBI surround the homes of & arrest, "Hillary Clinton, James Comey, James Clapper? People we know have also made false statements [to the FBI] – will the same standard apply?"

100% correct. pic.twitter.com/pRwGCYWcBU
