A source said on February 16: “President Trump has made it very clear that if Harry is found to have not told the truth on his visa application, then he could face prosecution.
Prince Harry would not say anything outwardly political although he did perhaps give the strongest hint of his real feelings to Mr Trump at the Invictus Games.
Whether affected by this or the Heritage Foundation, Mr Trump later changed his tune and suggested that he in fact would be taking potential issue over the visa.
If Harry answered the drugs question truthfully, that would have triggered a visa waiver process whereby he would have been interviewed and given a waiver.
He told athletes: “At this moment, when there is no shortage of crises, no absence of uncertainty, no lack of weak moral character in the world, the values you embody, the way you carry yourselves – not only at the Invictus Games, but each and every day – your courage, your resilience, your humanity, illuminate a path forward for us all.”.
