No escape for Trump: Comey's testimony is the biggest television event of the year

Additionally, the hearing will likely be covered on CNN, MSNBC, and Fox News, as well as on C-SPAN. The video will also stream on multiple online networks, including YouTube.

The much-anticipated hearing will be seen across the country, as well as internationally.

It is unusual for a congressional hearing to get the sort of coverage that disrupts daytime talk shows and soap operas. Historically, that level of interest has applied to events like the Clinton impeachment, Iran-Contra, and Watergate.

Given the green light to appear by special counsel Robert Mueller, Comey will testify about his allegation that Donald Trump leaned on him to publicly exonerate Trump from the investigation into connections between his presidential campaign and Russia.

Comey is unlikely to speak about details of the investigation, as it is still in progress. But regardless of what is said, a mass broadcast on a scandal like this only six months into his presidency is surely not something Trump ever wanted to happen.

For months Trump has denied that the investigation is of any consequence, blaming it on sour grapes from Democrats over the results of the election.

Now he will have to deal with it — with the whole world watching.
