Yesterday Trump gave a press conference in response to an explosive dossier about his ties to Russia.
The president-elect made clear that he suspected US intelligence agencies of releasing the 35-page dossier, which contained unverified allegations that Russia held compromising information which would render him vulnerable to blackmail.
He also took questions on his plans to give "complete and total" control of his business empire to his two eldest sons to avoid a conflict of interest.
However on Thursday the Office of Government Ethics slammed it as "meaningless" and said it "adds nothing to the equation".
American broadcaster and former General Synod member Christina Rees CBE told Premier's News Hour that she "really did not understand" why high profile Christians were not speaking on the issue.
She said: "There are ethical ways of behaving that reflect the standards we see in the Gospel of honesty and integrity that Trump just does not seem to be following at all.
"I think we're seeing a failure in leadership among some of the Christian churches and leaders.
"We all know, personally, sometimes it's really hard to say sorry when we got it wrong and to admit that we completely misunderstood something and to backtrack from a decision."
Trump branded the dossier "fake news" and said it would be a "tremendous blot" on the intelligence agencies' reputations if they were shown to have leaked it.
He also issued a series of tweets in which he denounced the document as "A COMPLETE AND TOTAL FABRICATION, UTTER NONSENSE".
"Intelligence agencies should never have allowed this fake news to 'leak' into the public. One last shot at me. Are we living in Nazi Germany?" he tweeted.
Russian president Vladimir Putin's spokesman Dmitry Peskov said the reports were "complete fabrication and utter nonsense" and the Russian government "does not engage in collecting compromising material".
Standing in front of a row of US flags, Mr Trump blamed the creation of the dossier on his political opponents, who he said had "got together - sick people - and they put that... together".
