One week after Education Secretary Betsy DeVos announced her department is changing controversial Title IX guidelines implemented under the Obama administration, 28 Democratic senators sent her a letter criticizing that decision.

The letter, sent Thursday, was signed by more than 60 percent of Democrats in the upper chamber, including prominent members such as Majority Leader Chuck Schumer, D-N.Y., Sen. Kirsten Gillibrand, D-N.Y., Sen. Dianne Feinstein, D-Calif., Sen. Kamala Harris, D-Calif., Sen. Claire McCaskill, D-Mo., Sen. Richard Blumenthal, D-Conn., and Sen. Al Franken, D-Minn. Independent Vermont Sen. Bernie Sanders added his support as well, bringing the total number of signatories to 29.
