It’s been nearly a month since President Trump fired former FBI Director James B. Comey. In the weeks since, the FBI has intensified its investigation into Russia’s efforts to influence the 2016 election and the possibility that it coordinated with people in Trump’s campaign. Public interest has been keen on Trump’s reasons for firing the FBI chief.

On Thursday, Comey is scheduled to testify before the Senate Intelligence Committee. How many questions will be fully answered remains unclear. What’s certain is that all of Washington, and the rest of the country, will wait with bated breath.
