Sen. Coburn taken to hospital

Sen. Tom Coburn (R-Okla.) was taken to a hospital Friday for tests.
 
"Dr. Coburn is having tests for a common arrhythmia and has not been admitted to the hospital," said John Hart, the senator's spokesman. Hart said Coburn expects to return to the Senate for Saturday's 11 a.m. vote on housing legislation.
 
{mosads}The 60-year-old Coburn, originally from Casper, Wyo., is an obstetrician and two-time cancer survivor known in the Senate for his penchant for putting "holds" on legislation. More than 80 holds are currently in effect, and the practice became a focal point of Senate debate this week when Majority Leader Harry Reid (D-Nev.) announced he was bundling 35 of the most popular bills into a "Coburn omnibus" and initially threatened to hold the chamber in session through the weekend.
 
Coburn has consistently defended his habit as necessary to ensure proposals receive proper discussion and debate.
