Ok, I think all you have to do is go online, and get a sense of why this is not great news. Yes, we all think Comey's a wanker who definitely helped influence the election negatively.(It's Time To Fight also has a copy of Trump's -- gobsmacking -- letter, if you haven't seen it yet, as well as other useful links and information.)
With that being said, we're not all outraged right now FOR Comey. I keep seeing people on the left and the right make this mistake. We're outraged over:
1) Why Comey was fired,
2) What it means that POTUS abused his powers like this.
3) Trump flat-out lied in his letter, and is trying to fool the masses.
Contact your representatives. Here's a suggested script (also from It's Time To Fight):
You: Hi, [my name is] and I’m calling from [zip code].A group are also working on organising marches/demonstrations for Saturday 3rd June to:
You: I’m asking [MoC/Senator] to push for a special prosecutor and an independent commission to investigate the Trump Administration.
You: The firing of Director Comey was a clearly a partisan act, based on false reasons. This reinforces the idea that we are in need of non-partisan investigations, urgently.
You: Please support this effort, and do what you can using the Ethics in Government Act. Please do what you can. Thanks. [hang up]
call for an impartial investigation into Russian interference in the US election and ties to Donald Trump, his administration and his associates.
