WASHINGTON, April 16, 2024 (BSS/AFP) - US House Speaker Mike Johnson said Monday that his Republican-controlled chamber would vote this week on separate aid bills for Ukraine and Israel, after stalling for months over pressure from his party's right-wing.

The US Senate passed a $95 billion package in February that included massive new funds to help Ukraine in its fight against Russia's invasion, as well as new support for Israel and Taiwan.

Johnson, leading a razor-thin Republican majority in the House, has refused to allow a vote in his chamber on the so-called security supplemental, despite urgent pleas from Ukrainian President Volodymyr Zelensky and other American allies.

Russia has regrouped amid the deadlock and gone on the offensive, with Ukraine suffering its first territorial setbacks in months after rationing ammunition due to shortages.

"We won't be voting on the Senate supplemental in its current form," Johnson told reporters Monday evening, "but we will vote on each of these measures separately in four different pieces."

He said that votes on the separate bills could occur by Friday evening, but that members would be allowed to offer amendments, which would likely drag out the process.

Johnson had previously opposed a standalone vote on Ukraine aid, demanding first that Democratic President Joe Biden crack down on illegal border crossings.

His sudden about-face comes after an unprecedented attack by Iran targeting Israel over the weekend, after which he pledged a prompt show of US support.

"There are precipitating events around the globe that we're all watching very carefully, and we know that the world is watching us to see how we react," he said Monday.

Earlier in the day, the White House ruled out any bill that only contained aid for Israel.

"We will not accept a standalone. A standalone would not help Israel and Ukraine," White House Press Secretary Karine Jean-Pierre told a briefing.

Johnson is walking a knife-edge on aid for Ukraine, as Donald Trump and far-right lawmakers in the House of Representatives have grown skeptical of pouring billions of dollars into Kyiv's fight against Russia's invading forces.

Ukraine has in recent months grown increasingly frustrated at delays in Western aid, including air defenses it says are urgently needed to repel Russian attacks.

Johnson, who rose from obscurity to take the gavel in October, continues to face a bid to oust him by far-right firebrand Marjorie Taylor Greene, who opposes any compromise with Democrats.

After a meeting of Republicans on Monday in which Johnson presented his legislative plan, Greene told reporters she was "firmly against the plan as it stands right now."

When asked if she was angered enough to pull the trigger on a procedural motion to force a vote on removing Johnson from his post, she said she was still undecided.

However, she said: "He's definitely not going to be speaker next Congress if we're lucky enough to have the majority."
