Yellow entity is first appearance of entity in passage:
The legal pressures facing [[P0]Michael Cohen] are growing in a wide-ranging investigation of [[P0]his] personal business affairs and [[P0]his] work on behalf of [[P0]his] former client, President Trump. In addition to [[P0]his] work for Mr. Trump, [[P0]he] pursued [[P0]his] own business interests, including ventures in real estate, personal loans and investments in taxi medallions.
Yellow entity is only appearance of entity in passage:
The legal pressures facing [[P0]Michael Cohen] are growing in a wide-ranging investigation of [[P0]his] personal business affairs and [[P0]his] work on behalf of [[P0]his] former client, President Trump. In addition to [[P0]his] work for Mr. Trump, [[P0]he] pursued [[P0]his] own business interests, including ventures in real estate, personal loans and investments in taxi medallions.
Yellow entity is invalid (doesn't refer to anything):

In addition to [[P0]his] work for Mr. Trump, [[P0]he] pursued [[P0]his] own business interests, including ventures in real estate, personal loans and investments in taxi medallions.
