Lawmakers hope a partisan dispute over Senate trial procedures for considering the House’s impeachment charges against President Donald Trump will be resolved this week. But a solution to the impasse could be complicated by another fight brewing in Congress over whether to restrain Trump’s ability to go to war with Iran.

Speaker Nancy Pelosi is holding the impeachment articles in the House in an effort to force Senate Republicans to agree to Democrats’ demands for certain witnesses and documents to be subpoenaed in the trial. The California Democrat has yet to indicate when she would transmit the articles to the Senate or lay out explicit conditions under which she would do so.

Pelosi has been more clear about her views on increasing U.S. tensions with Iran. The speaker announced Sunday that the House will vote this week on a war powers resolution to limit the president’s military response to Iran. The move comes after Trump authorized the killing in Iraq of Gen. Qassem Soleimani, leader of the Quds Force of Iran’s Islamic Revolutionary Guard Corps.
