Samuel Hook purchased the Silver Springs, Maryland, lobbying firm GrassRoots Interactive from Republican lawyer Edward B. Miller in September 2003, according to state documents, for a reported $10,000. 
Hook, who originally came to Greenberg Traurig after having worked at the now-defunct accounting firm Arthur Andersen, and his wife, Shana Tesler, were associates at the Greenberg Traurig law firm with indicted lobbyist and Republican fund-raiser Jack Abramoff. 
Tesler followed Abramoff from Greenberg Traurig to the lobbying firm Cassidy & Associates "after he was ousted from Greenberg [in March 2004] following news reports of his questionable dealings with Indian gaming tribes.
