U.S. House Speaker Mike Johnson said on Sunday he would work this week to advance wartime aid to Israel as part of his bid to win House approval of a national security package. It includes funding for Ukraine’s defensive war against Russia and funding for U.S. arms shipments to Taiwan.

The House speaker is under intense pressure to meet Republican opposition to a $95 billion package of supplemental U.S. aid to Ukraine, Israel and Taiwan, as well as civilians in Ukraine and Gaza. The bill has been stalled in Congress for two months.

Senior Republican lawmakers who support aid to Ukraine are growing increasingly frustrated with the months-long wait to bring the bill to the House floor. Kiev’s army is running low on ammunition, and Russia is making progress. Last week, a massive missile and drone attack destroyed one of Ukraine’s largest power plants and damaged others.

Separately, a growing number of hard-line conservatives have spoken out against Johnson’s toeing the Biden administration’s line on government spending.

Iran launched an unprecedented attack on Israel earlier Sunday, adding to pressure on Johnson but also giving him a platform to impress upon Congress the urgency of approving the funding.

“Details of the scheme are now being sorted out,” he said. “We’re looking at options and all these supplementary issues,” he told Fox News’ “Sunday Morning Futures.”

So far, the only aid package with broad bipartisan support in Congress is a Senate-passed bill that would provide about $60 billion to Ukraine and $14 billion to Israel, pending a decision by the House of Representatives.

White House national security spokesman John Kirby called on the House speaker to put the package on the floor “as soon as possible.”

“We don’t need any reminders about what’s going on in Ukraine,” Kirby said on NBC. “But last night really highlighted the threats that Israel faces in a very, very difficult neighborhood.”

With his job hanging in the balance and some Republican lawmakers calling for him to step down, Johnson is looking for ways to pass the bill that would provide some of the aid to Kyiv in the form of loans. He also supports using frozen Russian central bank assets.

Johnson also called for changes in U.S.-Mexico border policy. He has been in talks with the White House and former President Donald Trump, the Republican presidential nominee.

Many Democrats also said they might be willing to help Johnson defeat efforts to oust him from the speaker’s office if he brings the Senate bill to the Senate floor.

“I’m one of the people who would save him if we could solve Israel, Taiwan, Ukraine and some reasonable border security issues,” said Rep. Henry Cuellar, D-Texas.
