The head of the U.S. Senate's Democratic Party has called for the resignation of Israeli Prime Minister Netanyahu.

He said the PM is obstructing the realization of peace between Israel and the Palestinians. The comments were made in a speech to the Senate on Wednesday. The Senate is expected to vote on whether or not to impeach the PM in the next few days. The vote will be the first since Netanyahu was elected to the post in 2010. The next step is to hold a referendum on whether to remove the PM from office.
