On the contrary, it's quite relevant. I think you should read the Andy McCarthy article that you posted (including his link to John Sipher's analysis of the dossier's intelligence value) again. Particularly this part:
President Trump is uniquely positioned to reveal how the dossier was handled and what the FISA Court was told. As Congressman Jordan urges, Trump’s own FBI and Justice Department employees could easily let the Intelligence Committee examine any FISA applications derived from the dossier. Why doesn’t the president just order them to comply with Congress’s demand? In the unmasking controversy, it seems Trump was more interested in politically exploiting the specter of abusive unmasking than in ordering the disclosure of what actually happened. Is the same thing true of the dossier? I don’t know why the FBI and Justice Department are stonewalling the Intelligence Committee. Suffice it to say, however, that the president could order disclosure if he wanted to. He hasn’t. If he persists in that posture, we have to assume he would prefer that we not know what the FBI told the FISA Court.
