House Republicans on Monday introduced a plan to provide $14.3 billion in aid to Israel by cutting funding for the Internal Revenue Service, setting up a showdown with Democrats who control the Senate.

In one of the first major policy actions under new House Speaker Mike Johnson, Republicans unveiled a standalone supplemental spending bill only for Israel, despite Democratic President Joe Biden’s request for a $106 billion package that would include aid for Israel, Ukraine and border security.

Johnson, who voted against aid for Ukraine before he was elected House speaker last week, had said he wanted aid to Israel and Ukraine to be handled separately. He has said he wants more accountability for money that has been sent to the Kyiv government as it fights Russian invaders.
