TEL AVIV (JTA) — Secretary of State John Kerry said Israeli Prime Minister Benjamin Netanyahu is welcome to speak in the United States “at any time.”

Kerry’s statement Wednesday came after Speaker of the House John Boehner invited Netanyahu to speak to a joint session of Congress next month regarding Iran’s nuclear program. The Obama administration did not receive prior notice of the visit, which Kerry called “a little unusual,” according to Agence France-Presse.

On Wednesday, White House spokesman Josh Earnest said the invitation broke established protocol, as arrangements for Netanyahu to visit are generally coordinated with the Obama administration.
