A congresswoman picked by House Speaker Nancy Pelosi to oversee billions of dollars from the coronavirus relief package admitted she failed to disclose the sale of several stocks in 2019.

The Miami Herald published a report on Tuesday outlining several individual stock sales that Rep. Donna Shalala, a Florida Democrat, failed to disclose, as is mandated of members of Congress by the STOCK Act. The lawmaker sold off shares of Boeing, Alaska Airlines, Chevron, Conoco, and AMC throughout 2019 and did not report the transactions within 45 days as federal law requires.

"It was my mistake, and I take full responsibility," Shalala said in an interview with CBS Miami on Wednesday, claiming her intentions were good. She said she sold the stocks to avoid any potential conflicts of interest while serving in Congress.

"Look, I knew what the law was,” Shalala explained. “I missed the deadlines. And I have to take responsibility, personal responsibility for doing that. No one else is responsible except for me.”

Shalala, who took office in January 2019, said the reporting mishap happened because she did not include interim reports after filing her initial 2018 disclosure.

"I did file my disclosure report, so everybody knew what my holdings are. They didn’t know I was unloading the entire portfolio so I could put everything into mutual [funds] basically to avoid any conflict of interest," she said.

The congresswoman said she would be setting up a blind trust that would prevent her from knowing which sales are made to mitigate problems in the future. She also acknowledged that her reporting failure could lead to a criminal investigation and noted she alerted the House Ethics Committee about the situation and agreed to participate in any future investigations.

"Whatever they think is appropriate,” Shalala said. “Whether it’s a financial penalty or anything else. I’m really sorry I missed those deadlines in the process of trying to do the right thing.”

Shalala was one of the members chosen by Pelosi to join a select committee of House and Senate members who will oversee some of the funding disbursed to companies from the Treasury in the recent coronavirus economic relief package. Shalala argued that her reporting failures should not result in her removal from the committee.

"I don’t think so,” Shalala said. “We’re looking at how the secretary of the Treasury and the Fed gave out billions of dollars to bail out companies, including the airlines. What are the standards? What are the restrictions? Are they protecting workers in the process?”

Shalala was secretary of the Health and Human Services Department under President Bill Clinton and later served as president of the University of Miami and then the Clinton Foundation.
