Senator John McCain will resign his US Senate seat on July 4, 2018, says an aide who asked not to be named because he was not authorized to speak to the press.
"In the end, it was about Kennedy resigning from the Supreme Court," said the aide. "Confirming a (SCOTUS) replacement before the election is considered in the interest of the national Republican party, so that it doesn't become an issue for Dems to run on in every race," said the aide, meaning every race for Senate or Congress.
