Comey is expected to testify before Congress on Monday about President Trump’s claim that Trump Tower was wiretapped by the Obama administration during the election. According to ABC News, he is expected to debunk those claims within the first few minutes of his testimony.

During an appearance on NBC’s “Meet the Press” on Sunday, the House Intelligence Committee’s ranking Democrat California Rep. Adam Schiff said that he expects Comey will “put an end to this wild goose chase.”

“What the president said is patently false and the wrecking ball it created has now banged into the British allies and German allies and continuing to grow in terms of damage,” Schiff added.

Comey may also discuss whether or not the Trump campaign colluded with Russian government officials to try to hurt Clinton’s campaign and help Trump’s, a suspicion that has been exacerbated by a number of ties between individuals connected to Trump and both Russian dictator Vladimir Putin and WikiLeaks founders Julian Assange.

“If Comey acknowledges the investigation, it could balloon into a scandal for the still-young Trump administration,” wrote The New York Times on Monday.
