No… There is simply no doubt that there was Russian interference:

As set forth in detail in this report, the Special Counsel’s investigation established that Russia interfered in the 2016 presidential election principally through two operations. First, a Russian entity carried out a social media campaign that favored presidential candidate Donald J. Trump and disparaged presidential candidate Hillary Clinton. Second, a Russian intelligence service conducted computer-intrusion operations against entities, employees, and volunteers working on the Clinton Campaign and then released stolen documents. The investigation also identified numerous links between the Russian government and the Trump Campaign.

On February 16, 2018, a federal grand jury in the District of Columbia returned an indictment charging 13 Russian nationals and three Russian entities— including the Internet Research Agency (IRA) and Concord Management and Consulting LLC (Concord)—with violating U.S. criminal laws in order to interfere with U.S. elections and political processes.

The Mueller investigation couldn’t bring criminal charges of conspiracy against Manafort & co., but they obviously had contact and were found guilty lying about it.

But sure, giving these people the benefit of the doubt is completely normal behavior in 2026. You go on defending them as much as you want.
