A senior Donald Trump adviser is calling Hillary Clinton s decision to join a recount effort  incredible  and noting that the president-elect has not ruled out pursuing a criminal investigation into his former Democratic rival.Trump adviser Kellyanne Conway told CNN s  State of the Nation  that Trump has not ruled out a criminal probe into Clinton s use of a private email server as secretary of state, even though Trump recently indicated he d rather not do so.Conway said,  He s been incredibly gracious and magnanimous to Secretary Clinton at a time when, for whatever reason, her folks are saying they will join in a recount to try to somehow undo the 70-plus electoral votes that he beat her by. She added,  The idea that we are going to drag this out now where the president-elect has been incredibly magnanimous to the Clintons and to the Obamas is pretty incredible. Trump took to Twitter Sunday morning to condemn the Green-Party backed recount effort as  a scam.  Clinton s team joined the effort in Wisconsin after Green Party nominee Jill Stein filed paperwork formally requesting a recount.  AP
