President Trump is urging Congress to investigate the Ukraine impeachment "hoax" that was led by longtime foe Adam Schiff (D-CA) when he was still in the House, the New York Post reports.

“The Ukraine Impeachment (of me!) Scam was a far bigger Illegal Hoax than Watergate,” Trump wrote on Truth Social Sunday. “I sincerely hope the necessary authorities, including CONGRESS, are looking into this! Adam ‘Schiffty’ Schiff was sooo dishonest and corrupt.

“So many laws, and protocols, were violated, and just plain broken!!!”

Ukraine saga revisited

Schiff was one of the impeachment managers who led the case against Trump for abuse of power and obstruction of Congress. The Republican-controlled Senate acquitted Trump on both counts in early 2020.

Later, Schiff played a part in the January 6th committee's investigation, which followed a second, failed impeachment of Trump over the January 6th, 2021, protest at the Capitol.

The Ukraine controversy centered on a phone call between Trump and president Zelensky of Ukraine, in which Trump asked Zelensky for a "favor."

Democrats accused Trump of using military aid as leverage to dig up dirt on Joe Biden, who was emerging as a contender for the presidency as Trump faced re-election in 2020. Biden's business dealings were coming under scrutiny at the time, mostly from the right.

Biden infamously bragged about pressuring Ukraine to fire a prosecutor, Viktor Shokin, who had investigated Hunter Biden's energy firm Burisma Holdings. In the intervening years, more evidence has emerged of Biden's dubious dealings in Ukraine, which included phone calls with his son's business associates.

Newly declassified CIA files, which had been suppressed by Biden's national security team, indicate that President Petro Poroshenko and his officials were skeptical of Vice President Biden's "anti-corruption" work in Ukraine.

Schiff's abuses of power

While the details of the Ukraine impeachment saga have long been forgotten, the episode dominated headlines from the fall of 2019 until Trump's acquittal in February 2020. The impeachment launched the political careers of anti-Trump stalwarts like star witness Alexander Vindman and his brother, now-congressman Eugene Vindman, while raising now-Senator Schiff's profile as a partisan attack dog.

Schiff's role in the impeachment was scrutinized at the time by Republicans, who accused Schiff of collaborating with the so-called whistleblower at the center of it.

The whistleblower complaint emerged mere months after Schiff's false "Russian collusion" claims unraveled with the conclusion of Robert Mueller's investigation. Schiff selectively leaked intelligence to shape the collusion narrative that he publicly hyped, according to a former Democratic staffer on the House Intelligence Committee, where Schiff was the top Democrat.

While Trump demands retribution for the hoaxes in which Schiff played a part, the California Democrat could face charges over an unrelated matter.

Indeed, the Democrat is reportedly being investigated by the Justice Department for mortgage fraud.
