Good Brother, Bad Brother

[RJNorton]

I think the source of Mordaunt's claim is a story in the June 16, 1901, edition of the Chicago Inter-Ocean. The Inter-Ocean was a newspaper published in Chicago from 1865 to 1914. According to the story, Mordaunt went to the White House and was wandering through the rooms. Tad saw him, recognized him as an actor, and took him to meet his father. Mordaunt and Lincoln then had a conversation. According to Mordaunt, in the conversation Lincoln apparently said he had wanted to meet JWB, but that JWB had been avoiding his request to visit the White House.

Mordaunt describes Tad as "an an impulsive little fellow and spoke with a lisp which made it difficult to understand him." IMO, this gives the story some credibility.
