Senior White House adviser Calley Means said Thursday that "conversations are ongoing" regarding his sister Casey Means's nomination for surgeon general, amid questions about whether she has sufficient Senate support for confirmation.

Calley Means made the comments during an appearance on NewsNation's "The Hill" when asked whether the White House still expected Casey Means to become the next surgeon general.

The remarks suggest uncertainty around Casey Means's confirmation prospects in the Senate, though Calley Means did not elaborate on the specific nature of the ongoing discussions or what obstacles the nomination may be facing.

Casey Means was nominated for the surgeon general position, which requires Senate confirmation. The surgeon general serves as the leading spokesperson on matters of public health for the federal government.
