This is a Republican-led and Republican-majority committee. So, no blaming Democrats or the "fake news" for this:
While the GRU and WikiLeaks were releasing hacked documents, the Trump Campaign sought to maximize the impact of those leaks to aid Trump's electoral prospects. Staff on the Trump Campaign sought advance notice about WikiLeaks releases, created messaging strategies to promote and share the materials in anticipation of and following ther release, and encouraged further leaks. The Trump Campaign publicly undermined the attribution of the hack-and-leak campaign to Russia and was indifferent to whether it and WikiLeaks were furthering a Russian election interference effort.
Sounds like collusion to me.
