My husband was previously (2011,2013,2014) issued a B2 visa after having his ESTA application denied due to the moral turpitude question. He was given a B2 visa and we have travelled to the USA four times on this visa. This visa has since expired.
When doing my own ESTA now, I have noted that the question of moral turpitude has been removed from the ESTA application, so my husband should now pass the application. If he does so, will he be questioned or denied entry upon arrival in Hawaii as to why he previously had a B2 but now has an ESTA?
Also, for the question "Have you ever been denied a visa?" his answer is "no", isn't it? Because he was denied ESTA but granted a B2? He was never denied the B2 or entry to the USA previously. Only the ESTA was denied.
