If Trump were a smart, articulate, legally trained human (it's a big IF, I know), he would have answered the questions about his accusation with a quick summary of all of the information that led him to conclude that HIS CAMPAIGN was unethically and possibly illegally surveilled, both before and after his election win. This information was published a few days before the infamous TWEET by none other than Mark Levin, Esq., on his syndicated talk show.
The publication of detailed information about communications of his campaign staff and operatives logically leads to his conclusion.
In legal terms, he needed to lay out a "prima facia case" for his accusation. He could have, but he didn't.
Clearly, Democrats have real problems with the definitions of words. They use the Lewis Carroll system: "Words mean exactly what I want them to mean - no more and no less." Their definition of the word, "lie" is particularly problematic. Bush43 "lied" when he took action based on the intelligence findings of every major Western intelligence agency, namely that Saddam HAD caches of WMD's. Trump "lied" when he accused Obama or his operatives of "wiretapping" his offices and campaign.
But Barry Soetoro did NOT "lie" when he told Americans that their family health insurance cost would be reduced by $2,500/year under "Obamacare," even though he knew that this promise was total bullshit.
It is a puzzlement.
