Congress missed a deadline to reauthorize the CHIP program, which helps states provide inexpensive health insurance to children in low-income families.

Despite the Senate releasing a bipartisan bill to reauthorize the program for five years, a vote was never scheduled.

Three states and Washington, D.C., are expected to run out of money from the program by December, and the majority of states will run out by March, according to a July report from the Medicaid and CHIP Payment and Access Commission.

Another study by the Kaiser Family Foundation found that 10 states would run out money by the end of the year.

The deadline to reauthorize the program passed after Senate Republicans spent several weeks pushing to pass an ObamaCare repeal bill co-sponsored by GOP Sens.
