WASHINGTON (Reuters) - Republican Senator John McCain, who is receiving treatment for brain cancer and has missed votes this week, will be available next week to vote on the tax compromise bill, John Cornyn, the No. 2 Republican in the U.S. Senate, said on Thursday.

“He’s just resting up,” Cornyn said.
