What he said is that “Anti-Semitism is horrible, and it’s going to stop." He added that anti-Semitism was "age-old, and there's something going on that doesn't fully allow it to heal. Sometimes it gets better and then it busts apart."
Certainly this is hardly the soaring, eloquent level of response one hopes for from a president, but given his silence, at least it's something.
On the other hand, his comment that "there's something going on that doesn't fully allow it to heal" is tone-deaf. What's going on is that we had a presidential candidate who took a leading anti-Semite on to run his campaign (and then making him chief adviser) and stirred up up intolerance and racism in his run for the presidency and kept quoting from white supremacist website and in his refusal to denounce these groups throughout the race gave them winking approval that their actions could enter the mainstream.
That's what busts the healing about.
