The Trump administration's Medicaid director is leaving after less than three months on the job.

Mary Mayhew announced Friday her resignation as the director of the Center for Medicaid and CHIP Services (CMS).

“I appreciate her efforts at CMS and I look forward to continuing to work with her as she uses her many talents to help the state of Florida create a healthcare system that serves the needs of its citizens," Centers for Medicare & Medicaid Services (CMS) administrator Seema Verma said in a statement Friday.

Mayhew joined the administration in October to run Medicaid, the nation's health insurance program for low-income Americans.

She was previously the commissioner of Maine's Department of Health and Human Services, where she oversaw changes to the state's Medicaid program, including requiring monthly premiums and co-pays for services.

She opposed Medicaid expansion in Maine, and will likely push against any attempts in Florida to expand eligibility to more low-income adults.
