WASHINGTON — House Speaker Mike Johnson said Sunday he will try to advance wartime aid for Israel this week as he attempts the difficult task of winning House approval for a national security package that also includes funding for Ukraine and allies in Asia.

Johnson, R-La., is already under immense political pressure from his fellow GOP lawmakers as he tries to stretch between the Republican Party’s divided support for helping Kyiv defend itself from Moscow’s invasion. The Republican speaker has sat for two months on a $95 billion supplemental package that would send support to the U.S. allies, as well as provide humanitarian aid for civilians in Ukraine and Gaza and funding to replenish U.S. weapons provided to Taiwan.

The attack by Iran on Israel early Sunday further ratcheted up the pressure on Johnson, but also gave him an opportunity to underscore the urgency of approving the funding.

Johnson told Fox News Channel’s “Sunday Morning Futures” that he and Republicans “understand the necessity of standing with Israel” and he would try this week to advance the aid.

“The details of that package are being put together right now,” he said. “We’re looking at the options and all these supplemental issues.”

Senate Majority Leader Chuck Schumer at a news conference also said that President Biden held a phone call Sunday with the top Republicans and Democrats in the House and Senate, including Johnson. The New York Democrat said there was consensus “among all the leaders that we had to help Israel and help Ukraine, and now hopefully we can work that out and get this done next week.”

“It’s vital for the future of Ukraine, for Israel and the West,” Schumer said.

When he returns to Washington on Monday, Johnson will be facing a contingent of conservatives already angry with how he has led the House in maintaining much of the status quo both on government spending and more recently, a U.S. government surveillance tool.

Rep. Marjorie Taylor Greene, a right-wing Republican from Georgia, has called for Johnson’s ouster. She departed the Capitol on Friday telling reporters that support for her effort was growing. As Johnson on Sunday readied to advance the aid, Greene said on X that it was “antisemitic to make Israeli aid contingent” on aid for Ukraine.
