The whistleblower complaint that focused on President Donald Trump’s request of Ukraine’s government to investigate former Vice President Joe Biden also alleges White House officials moved the records of some of Trump’s communications with foreign officials onto a separate computer network, according to a published report.

The Washington Post, citing a person who has read the complaint, reported the whistleblower alleged officials moved communications from Trump’s July 25 call with Ukrainian President Volodymyr Zelensky onto a different network.

The Wall Street Journal reported the complaint involves more than one episode and is based on a series of events, according to several people who attended or were briefed on a meeting last week between the intelligence community inspector general and the House Intelligence Committee.

Trump defended his July phone call with Ukraine’s president, saying there was “no pressure” on him as a summary showed Trump urging his counterpart to open a probe related to Biden.
