From the White House:
"The Ethics in Government Act of 1978 requires high-level federal officials to publicly disclose their personal financial interests. The public filing system serves to prevent financial conflicts of interest by providing for a systematic review of the finances of government officials. Those finances are set forth in annual disclosures which are reviewed and certified by ethics officials. Neither the President nor the Vice President have any conflicts of interest, and their reports have been reviewed and certified by the independent Office of Government Ethics. We are continuing this Administration's practice of posting these forms online here in the interests of transparency":
