Washington (CNN) Senate Minority Leader Chuck Schumer said on Tuesday that he believes Democrats have the 51 votes necessary to pass a war powers resolution limiting President Donald Trump's ability to take military action against Iran without congressional approval.

"The Senate will soon consider Senator (Tim) Kaine's war power resolution, which would prevent further escalation of hostilities with Iran," the New York Democrat told reporters after Senate policy lunches.

"Senator Kaine sat down with Senators Paul and Lee and they came up with a resolution, which ripens Sunday, and we believe will get 51 votes that is needed to pass," Schumer said, referring to Republican Sens. Rand Paul of Kentucky and Mike Lee of Utah as well as Kaine, a Democrat from Virginia.

Schumer said the timing for a vote on the resolution still needs to be worked out and that they will have to figure out "how it intersects with impeachment."

Kaine told reporters, "We have been able to make some amendments that have earned the support first of Senators Lee and Paul, but now the support also of Senators Young and Collins," referring to Republican Sens. Todd Young of Indiana and Susan Collins of Maine.
