I have an urgent update, friend: Donald Trump is holding a rally in Florida this weekend. 

Republicans are terrified that their grip on Florida is in serious danger: It's why they're investing millions of dollars into registering record numbers of GOP voters. CNN is calling his good friend Marco Rubio one of the most vulnerable Senators in the country – and Florida Senate races come down to the margin of error (0.12 points in the last race). 

He's riling up his base because we're building the momentum to win – and the GOP is desperate to keep this seat red because Florida could determine Senate control. 

I have a major tailwind at my back because of grassroots donors like you, friend – but experts are predicting this will be the most expensive Senate race ever. And Trump, Mitch McConnell and GOP outside groups will continue to pour millions into this race and pull out every trick in the book to defeat me. 

I can't stand up to the millions of dollars the GOP will throw behind Marco Rubio alone. If I'm going to win in Florida and defend and expand our Senate majority, the work starts now. Tonight's rally proves it. 

You can help by pitching in a donation to hit our $150,000 rapid-response goal by midnight. Can I count on you to contribute $5 or more now to defeat Marco Rubio and protect our Democratic Senate majority?

Moments like this are a crucial test for our campaign – and whether we can muster the resources it truly takes to win and defend Democratic control of the Senate. I appreciate you doing your part and stepping up, and I'm so grateful for each and every member of this team.
