Sen. Susan Collins was one of 34 senators who voted against Geithner, while fellow Republican Sen. Olympia Snowe voted to confirm the New York Federal Reserve Bank president as Treasury chief.
Geithner won confirmation Monday despite personal tax lapses.
Collins said Geithner’s background and experience inspired confidence. But she said Geithner’s expertise was overshadowed by his handling of issues involving his own personal income tax returns.
Snowe pointed to Geithner’s experience in three presidential administrations, under five Treasury secretaries. She said his background would be invaluable in helping Congress and the Obama administration deal with the economic crisis.
