House Republican leaders have scheduled fast deliberation and a vote on the fiscal 2018 legislation authorizing the nation's intelligence operations, angering Democrats who now plan to block the measure on the House floor.

The Intelligence Authorization Act for Fiscal Year 2018 will be considered Monday under special rules prohibiting amendments, limiting debate to one hour and requiring a two-thirds majority for passage.

The House Intelligence Committee approved the bill unanimously on July 13.

But Democrats said Monday the limited consideration will prevent them from offering amendments.

In a letter to House Democrats, Minority Leader Nancy Pelosi, D-Calif., urged party lawmakers to vote against the legislation.

Because passage under "suspension of the rules." would require a two-thirds majority, Democratic opposition would block it.

"The Republican move to place this intelligence bill on Monday's suspension calendar would deprive Democrats of the ability to have a full and open debate on critical intelligence issues at this sensitive time in our nation's history," Pelosi said in memo to House Democrats on Monday.

"This is unacceptable when critical intelligence decisions are being made that impact America's national security, and while the House and Senate Intelligence Committees are leading investigations into Russia's continued efforts to undermine our democracy."

A spokesman for Majority Leader Kevin McCarthy, R-Calif., said he had no comment on Pelosi's memo.

The bill would authorize "resources and authorities" to the nation's intelligence agencies, including the CIA and Defense Intelligence Agency.

The bill "supports critical national security programs, particularly those focused on countering terrorism and cyberattacks," according to the committee.

Among the new provision in the fiscal 2018 measure is a requirement that the Intelligence Community provide reports to Congress about investigations of leaks of classified information, a problem that has plagued the Trump administration.

A spokesman for the House Intelligence Committee criticized Democrats for threatening to oppose the bill.

"It's appropriate for suspension because it's a crucial, non-controversial bill that passed twice on suspension last year and once on unanimous consent, and was approved in committee by a unanimous voice vote," Jack Langer said. "Nancy Pelosi herself said she's not objecting to the actual bill, so I guess she plans to play some political game today and then later vote for the same bill she's opposing now."
