The Biden administration will not say when the president plans on calling newly elected Israeli prime minister Benjamin Netanyahu to congratulate him on his victory, drawing accusations the U.S. administration is trying to isolate the conservative Jewish leader before he even takes office.

Asked on Thursday afternoon if President Joe Biden has any plans to phone Netanyahu following his victory this week in the Israeli elections, a White House spokesman told the Washington Free Beacon, “We don’t have any call to preview at this point.”

The Israeli media reported on Thursday that Biden is expected to call Netanyahu some time over the weekend, citing the U.S. president’s packed schedule campaigning around America’s midterm elections. But the White House would not confirm these reports when asked by the Free Beacon.
