Political caucus right after assassination

[Angela]

I found it – thanks to Eva!

It is quite detailed in the Journal of George W. Julian; here is his entry from April 15, 1865:

“Have spent most of the afternoon in caucus with Wade, Chandler, Covode, Judge Carter and Wilkinson, correspondent of The Tribune, who is determined to put Greeley on the war-path. In this caucus we agreed upon a new cabinet, which we are tomorrow to urge upon Johnson, among other things placing Butler in the State Department, Stebbins, of New York, in the navy, and Covode Postmaster General.
I like the radicalism of the members of this caucus, but have not in a long time heard so much profanity. It became intolerably disgusting. Their hostility towards Lincoln’s policy of conciliation and contempt for his weakness were undisguised; and the universal feeling among radical men here is that his death is a godsend.”

Thanks again all for the help!!!
I was really curious as to why it is never mentioned who attended, most biographies leave that out - but Julian listed the people there and the topics discussed.
