DENVER (AP) _ Things have been looking up for John Baron since flamboyant developer Donald Trump disclosed his favorite alias - John Baron.

Baron's mother calls him ''The John,'' he says his children look at him with new respect and his business partners toyed with the idea of renaming their management consulting firm Greenberg, Trump, Simon & Miller.

Trump acknowledged during testimony in a civil lawsuit in New York last week that he has used the name John Baron on occasion.

In a letter dated Wednesday, Baron wrote Trump that use of the alias has ''my mother very proud.''

''I ask only that you consider inviting my mother, the estimable Betty Baron, to lunch in New York as a way of thanking her. After all, it was she who came up with the name by which we both have prospered,'' he wrote.
