Vice President Mike Pence says the United States will open its embassy in Jerusalem next year, ahead of schedule.

In an address to the Knesset on Monday, Pence defended the decision to recognize Jerusalem as Israel’s capital, which has been condemned by the Palestinians and their Arab allies.

Pence says the administration will advance its plan in the coming weeks and the embassy will open by the end of 2019. Previous estimates had been the move would take three or four years.
