US Senate report goes beyond Mueller to lay bare Trump campaign's Russia links
Bipartisan intelligence panel says that Russian who worked on Trump’s 2016 bid was career spy, amid a stunning range of contacts

Bipartisan Senate report details Trump campaign contacts with Russia in 2016, adding to Mueller findings
The Senate Intelligence Committee released Tuesday the most comprehensive and meticulous examination to date explaining how Russia interfered in the 2016 presidential election and the Trump campaign welcomed the foreign adversary's help, revealing new information about contacts between Russian...

It goes into rather more detail than Mueller, explicitly detailing some of the involvement of Trump campaign staff with Russian operatives. Manafort, for instance, appears to have been communicating with, and handing information to, a Russian intelligence agent. Following the DNC server hack, the Trump campaign via Roger Stone was apparently acquiring advance information about released data from Wikileaks / Russia.
It is not pretty reading. The report strongly suggests that Trump lied to Mueller at least once, but there is nothing directly tying him personally to seeking assistance from Russia. However, it seems clear the Russians were able to carve straight into and exploit the Trump campaign. There is also criticism of the FBI, for taking the Steele dossier too seriously.
