Former U.S. President Bill Clinton and his wife Hillary collectively earned more than $30 million since January 2014, a financial disclosure form revealed. A Clinton campaign aide also confirmed that much of the couple's money came from their paid speeches.

A financial disclosure form provided to CNN, revealed that Hillary and Bill Clinton in total have made more than $30 million since January 2014.

The figures have been confirmed by a Clinton campaign aide. It was told that much couple's money came from paid speeches that were politically taxing for Hillary Clinton as she toured the country before running for President.

According to the form, the Clintons have given a total of 104 paid speeches since January 2014, netting the couple $25.3 million.

The form also showed that royalties and an advanced payment for Clinton's memoir 'Hard Choices' also brought in over $5 million.

Clinton filed the public financial disclosure report with the federal election Commission on Friday. This was done as it was required for any candidate who declared their presidential bid before April 15 and did not seek an extension.

Both paid speeches of Bill and Hillary Clinton are detailed in the report. The report showed that Hillary Clinton spent much of 2014 touring the country on the paid speaking circuit. Almost all of her speeches are domestic, expect for a few in Canada and Mexico.

Highest grossing speech for Hillary was at a $335,000 appearance at Qualcomm Incorporated in San Diego in October 2014, according to the form. The former secretary in total delivered 51 paid speeches.

Bill on the other hand was paid for a Bank of America speech in London, a food forum appearance in Sweden and a speech to a group of lawyers in The Netherlands.

Bill was even paid a sum of $175,000 for a speech in Miami where he appeared via satellite.

The form also gave details on the couple's investments. The couple has between $5 million and $25 million invested in a JP Morgan Chase cash account. They also have between $5 million and $25 million invested in a Vanguard 500 index fund.
