"I really do think we need to step back, look at what we're doing, and consider it," D.C. Council Member Mary Cheh said. "I don't think we should just forge ahead."
Cheh said she wants Mayor Muriel Bowser and the city council to discuss scaling back the commitment before the next city budget this spring.
Several council members have said they would support cutting back or even ending the street car project. Last year, D.C. Council Chairman Phil Mendelson slashed millions of dollars in future funding.
Bowser, who has instead praised express bus service over the street car, said she would review the street car effort. Council sources said one proposal would complete the planned line from H Street NE to Georgetown and a second line to Anacostia. Little other development is expected.
