A proposal to raise the income limits for families to qualify for D.C.’s controversial school vouchers program will be debated in the Senate this week, but the proposal has already drawn condemnation from the District’s congressional delegate.

Sen. Sam Brownback, R-Kansas, chairs the Senate subcommittee that oversees the District. He has said that the $14 million vouchers program needs to raise its income qualifications to keep students from leaving the program, which gives up to $7,500 to needy families to go to private schools.
