Actually you are completely wrong. The GOP members with the exception of Ros-Letinin only wanted to talk about leaks but that is not the reason for the hearing by the House Intelligence Committee.

The hearing was called with one specific purpose.. to investigate what role the Russians had in manipulating the US election. And who if anyone in the country either intentionally or ignorantly aided the Russians in that goal.

Here is the official committee announcement of the hearing... and you can look it up by clicking the link

"The House Permanent Select Committee on Intelligence (HPSCI) will be holding an open hearing on its investigation into Russian active measures during the 2016 election campaign.
The hearing will be held at 10:00 am on Monday, March 20 in room 1100 of the Longworth Building"

So I will await your admitting that your statement about the purpose of the hearing being one to investigate leaks being wrong.
