Sen. John McCain (R-AZ) makes remarks after receiving the the 2017 Liberty Medal from former Vice President Joe Biden (not shown) at the National Constitution Center on October 16, 2017 in Philadelphia, Pennsylvania.

Republican Sen. John McCain is returning to Arizona after being hospitalized for side effects from chemotherapy treatment for brain cancer, CBS News reported Sunday.

Senator McCain was diagnosed with cancer this summer.

McCain, who left Washington Sunday, will spend the holidays with his family. He will not be present for the final vote on the GOP tax bill expected early this week, the report added.

His vote is not expected to be critical to ensure passage of the tax bill. Senators Marco Rubio and Bob Corker last week both endorsed the bill, after initial opposition. Their endorsement is thought to ensure the legislation will become law.

Senator McCain’s office did not immediately respond to CNBC’s request for comment.
