Maybe you missed Murkowski's press release: "“Offensive and inappropriate statements made by Donald Trump throughout this campaign have caused me to withhold my support or an endorsement. I have always supported the Republican presidential nominee and I had hoped to do the same in 2016. The video that surfaced yesterday further revealed his true character. He not only objectified women, he bragged about preying upon them. I cannot and will not support Donald Trump for President – he has forfeited the right to be our party’s nominee. He must step aside.”
A bit more than a tweet.
