Robert Mueller appeared before Congress on Wednesday to testify about the probe and his 448-page report detailing the key findings of the investigation.
"The Russians are absolutely intent on trying to interfere with our elections through foreign influence," Christopher Wray said.
Robert Mueller will testify in back-to-back hearings on Wednesday about his two-year investigation into Russian interference in the 2016 election.
The hearing with the former special counsel was originally slated for Wednesday but has been pushed back by one week until July 24.
A senior official complained that anti-Russian sentiment was based on "completely artificially made up, manufactured and fabricated facts."
"I think the interference, although not yet quantified, if fully investigated would show that Trump didn't actually win the election in 2016," the former president said.
Robert Mueller's testimony will offer Democrats the first chance since the release of his report to directly question the former special counsel.
Special counsel Robert Mueller was issued with subpoenas to appear before Congress on July 17 by the House judiciary and intelligence committees.
"This isn't oversight, this is now try-to-harass-the-president time," Hannity said, reacting to Mueller's planned July appearances in front of Congress.
Sater "served as an informal agent of the Trump Organization in Moscow previously and had accompanied lvanka Trump and Donald Trump Jr. to Moscow in the mid-2000s," according to Robert Mueller's report.
President Trump said Obama "had to know" about the FBI "setup" to investigate his campaign and implied the former president may have helped initiate the Russia investigation.
Buttigieg said foreign interference in U.S. elections has "destabilized" America, and suggested Trump's statements jeopardized the "most sacred thing" in America.
Earlier this week, John Dean testified as a witness for House Democrats about alleged obstruction of justice by the president.
"It is almost unheard of for the Justice Department to release raw evidence to another entity so that the Justice Department can be second guessed," Andrew Napolitano said.
As he did some decades ago, former Nixon White House counsel John Dean found himself at the center of fierce criticism during testimony on Capitol Hill.
"I would be willing to personally indict the case and to try the case," Joyce White Vance, a former U.S. attorney, told Congress.
"Here's a guy who has no veracity at all. Nobody can trust what he says," Representative Andy Biggs of Arizona said.
Georgia congressman Rob Woodall said he also didn't read accusations against Bill Clinton in 1998.
Dean and other legal experts will testify before lawmakers about the lessons learned from special counsel Robert Mueller's report on the Russia investigation.
Rudy Giuliani is President Donald Trump's personal lawyer in his defense against the investigation by special counsel Robert Mueller.
A public testimony before Congress, Democrats argue, would better educate the American people about the cases of potential obstruction that may have gotten lost in the 448-page report and in which Mueller said he could neither exonerate nor charge the president over.
"He is basically nothing more than a political hatchet man trying to come out and say there was no obstruction of justice. All he's doing is making things up and essentially not following the law," one former federal prosecutor told Newsweek.
"Take the word impeachment away. It's a losing word," he said. "It's a 30-year-old word that does not help us."
In addition to the false claims, the president contradicted himself after publicly acknowledging—for the first time—in a tweet that "Russia help[ed] me to get elected."
"I had nothing to do with Russia helping me to get elected," Trump wrote on Twitter Thursday.
President Donald Trump's lawyer Rudy Giuliani lashed out at special counsel Robert Mueller following his statement at the Justice Department reiterating his report's findings.
The actor, who plays special counsel Robert Mueller in "Saturday Night Live" sketches, called on the prosecutor to speak publicly to Congress about his report.
"These facts that he laid out are so substantially similar to the matured allegations against Bill Clinton and Richard Nixon, it's clear where he was going," Andrew Napolitano explained.
"Mr. Mueller told us a lot of what we need to hear today," the chairman said when prompted whether he would subpoena the special counsel.
"After two years, the Special Counsel is moving on with his life," Sanders' statement read. "And everyone else should do the same."
