Computer code embedded in Clinton's email server, located at her house in upstate NY, copied "nearly all of her emails and forwarded them to the Chinese company", the website says.
Late Tuesday night, the president touted a "very big story" with a hacking accusation regarding Mrs. Clinton, a former Democratic presidential nominee.
In other words; Strzok, while investigating Clinton's email server, completely ignored the fact that most of Clinton's emails were sent to a foreign entity - while IG Horowitz simply didn't want to know about it. "Much classified information!" Trump tweeted on Tuesday.
Trump's claims, which he provided no evidence for, appear to be based on a report from conservative blog the Daily Caller.
During the 2016 campaign, in which Trump faced off against Clinton, then-FBI Director James Comey announced that the agency had found no basis to bring criminal charges against Clinton, the Democratic nominee.
He recently tweeted that "at some point" he "may have to get involved".
A Justice Department spokesman did not immediately respond to a request for comment.
Trump has been a vocal critic of the FBI's handling of the Clinton email investigation.
Strzok is a disgraced former member of FBI Special Counsel Robert Mueller's team, which has been seeking evidence of US President Donald Trump's collusion with the Russians to no avail so far.
"This isn't the first time that we've heard this kind of accusation", Hua told a daily news briefing. She said China is a staunch defender of cybersecurity.
He drew media ridicule for holding up a chart past year at a House Judiciary Committee hearing that connected Justice Department officials, a Uranium company, former attorney general Eric Holder, Benghazi, political intelligence firm Fusion GPS, Clinton's secret server, Bill Clinton, the IRS targeting scandal, and other topics. Also, given that his administration remains under intense scrutiny for its ties to Russia, Trump offered up a different scapegoat.
