Ok, we just disagree. I think in times of crisis, advice from those that have been there should be considered by the new person. And there is, independent of that, value in doing so for the sake of continuity.
That is especially so in the case of a nationwide and worldwide crisis. GWB dealt with 9/11 and all of the politics of that and saw first hand how partisanship can inhibit an effective response, in both directions. I think it benefits the office and respect for the office to accept the advice graciously, even if you don't agree.
But I don't know that anyone has ever said, or ever will, that Trump takes advice graciously and especially if he thinks that buried within it is the notion that his actions so far have perhaps not been up to snuff.
That's a partisan political issue and I think Trump is free to complain that people within the Republican party should have uniformly stood behind him. Obviously, not everyone was okay with what he did. See e.g. Romney. Trump certainly has the right to complain about that, though of course I admire those GOPers who stood up to him, then and at other times, over those who cowered in the corner.
I just don't think that it was the right time to bash him when all he did was offer advice and encouragement to Trump and to everyone else to put partisanship aside for the time being.
