All of it. When you lie to FISC to get a FISA warrant, the spying that results is illegal.
What lies to get the FISA warrant?
Illegal Spying By Corrupt FBI

Today the FISA court published the declassified and redacted version of a two-page order on the Carter Page FISA warrants (embedded at link.) “At least” two of the four warrants approved by the FISA court lacked probable cause and were therefore illegal. Rulings have not yet been issued on the other 2.
This court order provides a timely reminder that the biggest scandal in American political history implicates the Obama administration, not the Trump administration. Adam Schiff, now presenting the case for Trump’s removal from office, made his bones obstructing the investigation of, and lying about, that particular scandal — the scandal of which President Trump was the intended victim. The unraveling of the scandal proceeds offstage and out of the spotlight.
LOL- I love the hype 'biggest scandal in American political history'.
Once again- no one has found any corrupt intent by the FBI- nor any actual conspiracy, especially no evidence of your "Deep State"
Meanwhile we have the actual President of the United States pressuring a foreign government to interfere in the American election.
Trump was correct to suggest Ukraine get to the bottom of the obvious Biden corruption and extortion.
It's fascinating what a bubble these folks are in.
SUGGESTED? NO. FLAT-OUT SAID IT? YES.
Biden Still in Denial, Says ‘No One Has Suggested My Son Did Anything Wrong.’
Everyone knows that Hunter is a loser and and a deadbeat who collected $Millions from foreign interests in an influence scheme while pops was VP.
Everyone knows that Biden, as VP, extorted Ukraine, using a $Billion in US aid, to fire the prosecutor that was investigating the Biden Family corruption. This is as true as Russian Collusion was always false.
The
Washington Post noted that earlier this week that Biden was aggressively defending Hunter, even referring to him as “my only surviving son” in reference his older son Beau, who died in 2015. An obvious attempt to generate sympathy in light of the attacks on Hunter's shady business dealings.
On Friday, Jonathan Turley called Biden out over his repeated denials and weak defenses of his son's business dealings. "Joe Biden continues to maintain that
'no one' has accused his son of wrongdoing when there is a chorus of such allegations," Turley said, also noting:
The most interesting thing about Biden's recent comments is that he acknowledges it "looked bad that he was there." Doesn't that seem to suggest that an investigation is necessary? Democrats argued that the call between Trump and Zelenksy looked bad, and required an investigation.
Trump was COMPLETELY RIGHT to suggest a recommendation to his fellow president. Democrats are pretending that even suggesting something that is obviously correct, but, which they don't want stated, is an impeachable offense.
Well, the Democrats claim is about to be tested by a US Senate vote and our Beloved President will be wholly vindicated, and Democrats will have their noses firmly rubbed in their own crap.
Biden's position didn't just "look bad." Quid Pro Quo Joe Biden pressured the Ukrainian government to fire the prosecutor investigating Burisma while his son was on the board—and that prosecutor confirmed that Biden's pressure
was responsible for his dismissal. But, Burisma was still involved in shady deals, and Ukrainian officials
had opened a new investigation of Burisma months before Trump's infamous call with Zelensky. There is also evidence that Burisma
leveraged Hunter Biden's position on the board to pressure the Obama administration to quash corruption allegations against them.
It doesn't take Einstein to realize something shady was going on with Hunter Biden getting a cushy job making $80,000 a month to sit on the board of a business he knew nothing about at the same time the company was pressuring the Obama administration to quash an investigation into their corruption—which they successfully did.
Biden is clearly in denial, and, so are you and your fellow travelers. You fully and completely deserve what's coming. The US Electorate sees through this nonsense, completely.
