From a White House Blog Post:
On Ethics.gov, the public will be able to find millions of White House Visitor records. You will be able to see agency reports of payments from non-Federal sources for travel to meetings and conferences.
You’ll find records for entities registered with the Federal Election Commission. This includes federal political action committees and party committees, campaign committees for presidential, House and Senate candidates, as well as groups or organizations who are spending money in connection with elections for federal office.
You’ll also find records for each candidate who has either registered with the Federal Election Commission or appeared on a ballot list prepared by a state elections office. This includes contributor information for each contribution of $200 or more from an individual to a federal committee.
You’ll also be able to find lobbying registrations and reports filed under the Lobbying Disclosure Act.
