In the committee or any committee, is it possible they will hear what somebody swears that they heard, where as in a court of law hears say evidence not allowed to stand. I do not know if this is the case or not, as far as committees looking into whether to refer charges to the Justice department or not, but very well could be, as this is just a congressional inquiry, not a court of law, where the outcome decisions mean jail time, not a referral to Department of Justice for charges. If a referral is made, I doubt here say evidence would be used in the referral. If it is, DOJ would have to investigate to see if they wish to prove it true or false in a court, in front of a jury and a judge that can levy criminal penalty based on outcome.
Personally, I would be very interested to hear the agents testify yea or nay under oath, as what they say in the to newspapers is immaterial as to truth, as they can lie to newspaper reporters all they want.
Another thing I would be interested to see would be a lawsuit filed by the agents, against the young lady if they think it makes them look bad in the public eye, as lawsuits are very popular with Republicans, as we saw in the days after the election, that is until the cases were fast tracked and lawyers declined to argue their assertions, in front of a judge.
