In a world dominated by instant-access to information and social media dominates most American's intake of "news"....
The actual legal process is slooooowww and BORING. Sad to say that unless Bolton has emails, texts, notes to corroborate his claims, no one is going to care much aside from how they already feel about Trump.
Which also bothers me about the whole Trump Impeachment process over the last 3 years - how is it that our entire U.S. government is run without any paper trails or data traces? Is Trump calling executive privledge over everything? Talks a lot of bluster about his opponents but quietly ExecPriv's against any REAL incriminating evidence?
Otherwise, are Trump's cabinet members and trusted advisers really just doing everything Trump says without any backup in writing? For all the crowing about Hillary's emails years ago, where is anything that Trump tells someone else to do in writing?
