On Friday, Donald Trump dismissed Lt. Col. Alex Vindman from the National Security Council, months before his tenure was set to expire. Trump sacked Vindman, a Purple Heart recipient and the White House’s top expert on Ukraine, for his courageous testimony during impeachment proceedings in November, when he told Congress he’d reported his concerns about Trump’s now-notorious July 25 phone call with Ukrainian President Volodymyr Zelensky.

But who’s truly to blame for this naked act of thuggish retaliation? All 52 Republican senators who voted to acquit Trump for his abuses of power and desperate attempts to cover them up. Most especially, that includes the vulnerable Republicans who are up for re-election this November:

Susan Collins in Maine Joni Ernst in Iowa Cory Gardner in Colorado Kelly Loeffler in Georgia Martha McSally in Arizona David Perdue in Georgia Thom Tillis in North Carolina

Collins is particularly egregious: On Friday morning, before the Vindman news broke, she told reporters, “I obviously am not in favor of any kind of retribution against anyone who came forward with evidence.” What’s transpired since was not only predictable, it had in fact been predicted. Collins and her brethren knew what would happen as a consequence of vindicating Trump. They simply didn’t care.

We, however, do. Every time Trump does something awful from this day forward, we know whom to hold responsible. And we can ensure that his enablers go down to defeat this fall.
