It looks like Trump’s absurd attack on the Trump University judge are finally taking it’s toll:

First un-endorsement — Sen. Mark Kirk. "I cannot and will not support my party's nominee for President." — Erica Werner (@ericawerner) June 7, 2016

Sen. Mark Kirk reverses decision to endorse Trump https://t.co/5oSrITow3s — MSNBC (@MSNBC) June 7, 2016

Earlier his opponent had attacked him for his silence:

Any politician, Mark Kirk included, who stays silent, or hopes to fly under the radar, is complicit in Trump's campaign of hate and division — Tammy Duckworth (@TammyforIL) June 6, 2016

Given my military experience, Donald Trump does not have the temperament to command our military or our nuclear arsenal. — Mark Kirk (@MarkKirk) June 7, 2016

Damn. Is there any way to walk that back? Sounds very doubtful….
