US Sen. Coburn to retire after current session

OKLAHOMA CITY (AP) — U.S. Sen. Tom Coburn will finish out the current congressional session and then resign from his seat nearly two years before his term is scheduled to end, he said in a statement released late Thursday.

The 65-year-old Republican said he would give up his seat at the end of the current session in January 2015. His term was scheduled to end in 2016, and Coburn already had vowed not to seek a third.

Coburn recently was diagnosed with a recurrence of prostate cancer, but said his decision was not about his health.

Known as a conservative maverick during his three terms in the U.S. House in the 1990s, Coburn continued that role after being elected to the Senate in 2004. He was a fierce critic of what he described as excessive government spending, and was most vocal about opposing the earmarking of special projects.
