The big news from the White House excerpts is that President Obama will directly rebuke the Supreme Court -- to their faces -- by saying that their ruling in Citizens United overturned a "century of precedent" and opened the "floodgates" for money from corporations and unions to pour into politics. He'll also urge Congress to pass a law prohibiting companies with foreign shareholders from contributing to politics. (Drawing the lines here is going to be tough.) Note that the White House is preparing for a Supreme Court vacancy (or two) this summer, so Obama's remarks here have particular salience.
The White House is pointing reporters to Obama's call for Congress to require lobbyists to disclose all their contacts with White House officials and members of Congress.
