WASHINGTON, D.C. (WVEC) -- One day to go until former F.B.I director James Comey's potentially explosive testimony on Capitol Hill.

Virginia Senator Tim Kaine for one, hopes to get some answers.

In his prepared remarks released today, Comey will testify that President Trump, during a dinner on January 27, told the then-F.B.I director: "I need loyalty. I expect loyalty."

Comey will also testify about a February 14 White House meeting with the President.

In the meeting, Trump apparently tried to persuade Comey to drop any further investigation of former National Security advisor Michael Flynn.

According to Comey's statement, President Trump said:

"I hope you can see your way clear to letting this go, to letting Flynn go."

Virginia Senator Tim Kaine said reports of what Trump may or may not have done to influence Comey's investigation into possible collusion between the Trump campaign and Russians in the 2016 election, are highly troubling."

"We're talking about potential obstruction of justice, potential espionage, potential treason, potential conflict of interest, potential perjury or failure to at least accurately report," he said. "None of these things have been proven, but they're all very serious and we have to get to the bottom of it."

Kaine said it is urgent that senators and the American public hear directly from Comey about the allegations.

"I don't know if they're true, and that's why hearings like today are so important," he said. "The allegations are highly troubling. the reporting seems well-sourced. But that's not the same as proof."
