Will Thursday's testimony end the Russian interference investigation?

On Thursday, testimony was given that pointed to the dossier that has been the cornerstone of the Trump/Russia collusion accusations was actually created by the Russians and was created on behalf of a group (Fusion GPS) that has strong ties to the Democrats and particularly to Hillary Clinton. As of today, trying to find stories about the Russian collusion investigation on CNN, ABC, and MSNBC is very difficult. Will this testimony mean that the whole thing will be dropped so further investigations that might lead towards the Democrats won’t happen?
