A look at one of the key Senate races: Sen. Mitch McConnell vs. Alison Lundergan Grimes.
San Francisco (CNN) - Leland Yee needed cash.
First, the ambitious California state senator had to fund his 2011 race for mayor of San Francisco. When he came in fifth, he was stuck with $70,000 in campaign debt that he had to retire before he could mount his next run, for secretary of state - a costly statewide venture.
And that's how prosecutors say Yee ended up sitting across from an undercover federal agent in a coffee shop in early March, brokering what he was told was a $2 million arms deal that would include the purchase of shoulder-fired missiles from Islamic rebels in the Philippines.
