Analysis: Press Conferences
Press conferences given by the President can be found at the Whitehouse's website whitehouse.gov They appear in the form of news releases. The one I have linked above is a verbatim transcript of the press conference.
I unfortunately had a hard time finding articles that covered certainly press conferences that were held recently or quoted material was not directly attributed to the press conference itself.
I found one article that, relatively recently quoted a press conference in Toronto, from Reuters The article covered an issue more so than the press conference itself. The article used quotes from the press conference as simply one aspect of information that contributed to the larger story.
From searching for coverage of press conferences I learned to look at them and treat them mostly as news releases where most of the provided information is previously planned.
