President Donald Trump has not made a final decision on whether to carry out new strikes against Iran, according to two diplomats briefed on the matter.
The FEC tracks campaign spending by candidates and political committees but does not administer US elections. The disruption is therefore not expected to affect voters' ability to cast their ballots.
The Iran war, which Trump often describes as a "little detour", has emerged as an unforced liability for the president, who once promised to keep the US out of foreign wars.
Much of the House Democrats' agenda, if they regain power, would depend on the size of the majority. Details also depend on the Senate, and whether it flips to Democrats.
Trump has been threatening that a post-midterm election escalation in the war remains a viable option, despite his initial promises that a military campaign would last a matter of weeks.
Democrats freely acknowledge their disadvantage, relying instead on anti-Trump sentiment among voters and targeted messaging on issues like corruption.
