Before being elected to Congress in 2012, Maryland Rep. John Delaney founded and led CapitalSource Inc., which makes commercial loans to small and middle-market businesses nationwide. Prior to that, he founded HealthCare Financial Partners, which provided financing to the healthcare firms.

Delaney held partnership or director positions in a variety of financial companies, according to his 2012 financial disclosure forms. He stepped down as chairman of CapitalSource before taking office.

The vast majority of Delaney's assets, which total between $70.7 and $245.3 million, are in the financial sector.

His main debts are a mortgage of between $1 million and $5 million and a loan from a family trust in the same range.
