Steve Bannon and Michael Flynn have been subpoenaed as part of voting company Smartmatic’s $2.7 billion defamation lawsuit against Fox Corporation and others, according to newly filed court papers.

The allies of former president Donald Trump were vocal supporters of Trump’s false claims that the 2020 U.S. Presidential election was stolen through widespread voting fraud. Bannon previously served as a White House strategist in the Trump Administration, while Flynn spent a brief period as national security advisor.
