former u.s. senior official under the obama administration saying quotining now, just nonsense in reference to this wiretapping allegation. from president trump. on president obama. how potentially damaging is this for the sitting president now to make these accusations about his predecessor? >> the first thing i'd say is that you know president trump can find out the answer. richard nixon had a top secret investigation. of the intelligence community. started after he became president. to find out if they wiretapped him during the '68 campaign. and he diskickoffed they hadn't. now, then he started fake news and would say he had been wiretapped. it wasn't true. he knew it wasn't true. that report was declassified a couple of years ago. donald trump could actually find out what fisa warrants had been issued. he has the power as president.
