The $100 million couple

Hillary Clinton is trying to appeal to working-class voters for Pennsylvania's April 22 primary, and the campaign appeared to try to downplay the Clinton's wealth by releasing the data on a busy Friday evening, while most of the major news outlets were covering the 40th anniversary of the assassination of Dr. Martin Luther King, Jr.

The Clinton campaign also played down the significance of the $109 million figure by emphasizing the couple's after-tax earnings ($57,157,297) and their charitable contributions.

"What the Clintons' tax returns show is that they paid more than $33,000,000 in federal taxes and donated more than $10,000,000 to charities over the past eight years," said Carson. "They paid taxes and made charitable contributions at a higher rate than taxpayers at their income level," he added.

The release of the documents fueled speculation and questions by some observers, who focused on the source of President Clinton's $52 million in income from speaking engagements.

  The Los Angeles Times reported that the Clintons claimed more just for cleaning and maintaining their homes than the $44,000 average family income in Pennsylvania.
