You have an error in your SQL syntax WHERE ID IN

Мой sql запрос

$ru_str = "(310,350,69)";

$sql = 'SELECT * FROM posts WHERE status="publish" AND WHERE ID IN ('. $ru_str .') order by ID desc ';

при выполнении запроса выдает ошибку

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE ID IN (310,350,69,65,285,367,396,410,421,420,419,418,428,429,430,431,436,4' at line 1 

По отдельности эти запросы выполняются WHERE status="publish" WHERE ID IN ('. $ru_str .') как только ставлю между ними AND, ошибка
