READ: Defense Secretary Mattis’s resignation letter

Defense Secretary James Mattis announced Thursday that he would resign in February, sending a letter to President Trump stating that he deserved a general “whose views are better aligned with yours.”

In his resignation letter to Trump, Mattis said he was resigning “Because you have a right to have a Secretary of Defense whose views are better aligned with yours.”

His letter was released minutes after Trump said on Twitter that Mattis was “retiring.”
