It's been more than a year since Metropolitan Police Department officers were ordered to stop using the breathalyzers because the blood-alcohol testing machines were not calibrated properly. It was a revelation that has called into question hundreds of drunk driving convictions.
D.C. Council member Phil Mendelson says he's holding the hearing to "prod" authorities to get the program back up and running.
Without accurate breathalyzers, police have had to rely on urine tests to build cases against suspected drunken drivers -- a technique that is more expensive and time consuming than a breathalyzer test.
Mendelson has been trying to get D.C.'s Attorney General to establish a time line for fixing problem and says he wants to see more progress.
The hearing is scheduled for 10 a.m.
