After the hoo-raw that rose over Dean’s scurrilous accusation, Dean said this to MSNBC‘s Stephanie Ruhle:
I apologize for using innuendo. I don’t think it’s a good thing to do, I don’t think it’s the right thing to do…. I’m not unwilling to apologize for using innuendo.
Notice that. Dean apologized for beating around the bush (which he didn’t actually do; Dean was quite direct in that tweet of his) with his accusation about Trump being on cocaine.
But Dean has not a syllable of apology for his actual accusation. Masquerading that statement as an apology for his accusation is a base lie.
