Senate Democrats are questioning if the Trump administration will protect individuals against discrimination in healthcare.

The Democrats' letter sent to Health and Human Services Secretary Tom Price on Monday was in response to changes to the HHS website and recent hires. It comes a few months before the start of Obamacare's open enrollment on Nov. 1.

Senate Democrats originally wrote to HHS on May 10 after changes to the agency's website removed language on Obamacare regulations that prohibit discrimination in healthcare related to race, color, national origin, sex, age, and disability.

Democrats were perturbed that they didn't get a response from HHS. They were also upset that the department removed language that clarifies that discrimination based on gender identity and sex stereotyping constitutes discrimination.

"As of today, the website mentions only discrimination on the basis of pregnancy as a type of sex discrimination," the senators said.

In May, the senators said they were concerned about the removal of language from a frequently asked question.

Democrats also pointed to the decision to hire Roger Severino to head HHS' Office of Civil Rights. They say Severino previously praised government officials for refusing to provide marriage licenses to same-sex couples.

HHS did not immediately return a request for comment.

Democratic Sens. Patty Murray of Washington and Richard Blumenthal of Connecticut led the letter signed by 15 senators.
