Did Rathbone get blamed?

[L Verge]

It's interesting that Tom mentioned issues that Rathbone may have had with his stepfather. I was reading something the other day (and I can't remember what, as usual) that described the confrontation that Senator Harris had with Mary Lincoln and her sister when the Confederate widow was visiting the White House. For some reason, I knew that this incident had occurred, but it never stuck in my mind that two of the "gentlemen" involved were Senator Ira Harris and Gen Dan Sickles. If the dialogue was as portrayed in the accounts, this is one time we have to give Mrs. Lincoln credit for maintaining her cool. Harris, especially, comes off as a rude and arrogant man.

I know that Harris replaced Seward as New York's Senator when Seward took higher office, but has anything been written on him as to what kind of politician and man he was? If he was this high-handed, perhaps that contributed to some of Henry's emotional and psychological problems?
