On Monday, the House Intelligence Committee holds its first hearing on Russia’s hacking of the election. (No date has yet been set for the Senate Intelligence Committee’s parallel investigation.) The list of initial witnesses does not inspire confidence in the House committee’s effectiveness.

It should be relatively easy to get at the truth of whether there was collusion between the Trump campaign and Russia over the hacking. I have some relevant experience. When I was a member of Parliament in Britain, I took part in a select committee investigating allegations of phone hacking by the News Corporation. Today, as a New York-based journalist (who, in fact, now works at News Corp.), I have followed the Russian hacking story closely. In November, I broke the story that a Foreign Intelligence Surveillance Act court had issued a warrant that enabled the F.B.I. to examine communications between “U.S. persons” in the Trump campaign relating to Russia-linked banks.

So, I have some ideas for how the House committee members should proceed. If I were Adam Schiff, the leading Democrat on the committee, I would demand to see the following witnesses: Carter Page, Paul Manafort, Richard Burt, Erik Prince, Dan Scavino, Brad Parscale, Roger Stone, Corey Lewandowski, Boris Epshteyn, Rudolph Giuliani, Michael Flynn, Michael Flynn Jr., Felix Sater, Dmitry Rybolovlev, Michael Cohen, Jack Dorsey, Mark Zuckerberg, Peter Thiel, Robert and Rebekah Mercer, Stephen Bannon, Sebastian Gorka, Michael Anton, Julia Hahn and Stephen Miller, along with executives from Cambridge Analytica, Alfa Bank, Silicon Valley Bank and Spectrum Health.

There are many more who need to be called, but these would be a first step. As to lines of questioning, here are some suggestions.
