Schiff was elected to the Senate last year but served in the House while Congress investigated whether Trump colluded with Russia to influence the 2016 election.

And as a ranking member and then chair of the House Intelligence Committee, Schiff was directly involved in the congressional investigation and became a leading Democratic voice accusing Trump's 2016 presidential campaign of colluding with Russia.
"Should Obama and his team be held responsible in some way for pushing the Russia collusion narrative that was proven false to take down Trump?" Fox News Digital asked Schiff.
"Well, if you read the well-reported intelligence community report, you know they documented Russia's efforts to help denigrate Hillary Clinton, which gave a boost to the Trump campaign," Schiff responded.
Schiff was referring to an Intelligence Community Assessment report from 2017 that asserted that Russia's goals were to undermine faith in the U.S. democratic process and to "denigrate" former Secretary of State Hillary Clinton, and that Russian President Vladimir Putin "developed a clear preference" for Trump.

"Adam ‘Shifty’ Schiff is in BIG TROUBLE!" Trump said on Truth Social on Sunday. "He falsified Loan Documents. He once said my son would go to prison on a SCAM that Schiff, along with other Crooked Dems, illegally ‘manufactured’ in order to stage an actual coup."
"My son did nothing wrong, knew nothing about the fictional story," he added. "It was an American Tragedy! Now Shifty should pay the price of prison for a real crime, not one made up by the corrupt accusers!"
The U.S. Federal Housing Finance Agency (FHFA) sent a letter to the Department of Justice in May alleging that Schiff has "falsified bank documents and property records to acquire more favorable loan terms, impacting payments from 2003-2019 for a Potomac, Maryland-based property."

"Since I led his first impeachment, Trump has repeatedly called for me to be arrested for treason," Schiff said after Trump first accused Schiff of mortgage fraud. "So in a way, I guess this is a bit of a letdown. And this baseless attempt at political retribution won’t stop me from holding him accountable. Not by a long shot."
