As President Donald Trump prodded his Ukraine counterpart to investigate his potential 2020 Democratic rival, Joe Biden , he also made another request, one that stems from outlandish conspiracy notions that Trump has embraced and emboldened in recent years.

According to the summary the White House released Wednesday of a July 25 conversation between Trump and Ukraine President Volodymyr Zelensky, the U.S. president also wanted the European nation to investigate CrowdStrike, the California-based cybersecurity firm that investigated the 2016 hack of the Democratic National Committee and concluded that Russian intelligence operatives were responsible for the breach.

Trumps focus on an investigation targeting Biden in the conversation, as well as the former vice presidents son, Hunter, has spurred House Speaker Nancy Pelosi (D-Calif.) to open a formal impeachment inquiry.
