If you only read one thing: Hillary Clinton and Bernie Sanders will try to present a unified front Tuesday as he formally endorses her after their long and sometimes bitter primary. While Clinton effectively locked up the nomination months ago, Sanders’ refusal to step aside and continued pressure on Clinton from the left has had a clear impact on the presumptive Democratic nominee. The party’s platform is the most progressive ever, while Clinton has set aside her pragmatic agenda to embrace a pie-in-the-sky Sanders proposal that launched him into serious contention and made him a darling of Democratic youth: free college. There is little love lost between the two Democrats, and Sanders has expressed a desire to keep pulling Clinton to the left, even after he formally quits the race. Sanders’ legacy within the Democratic party will be felt for a long time—though it remains to be seen how long. As Clinton prepares to roll out her vice presidential selection and formally accept the nomination in Philadelphia later this month, it remains to be seen whether the progressive turn will hurt her with the independents she needs to win in November.

The Republican Party platform took a rightward turn Monday, as it reaffirmed its opposition to same-sex marriage and toughened language off an initial draft on same-sex couples. Social conservatives also secured an endorsement for parents’ rights to put their children through controversial conversion “therapy.” Meanwhile, party leaders were able to scale back language that would have explicitly called for legislation along the lines of North Carolina’s HB2—the bathroom bill—but maintains a protest against the Obama administration’s efforts to use Title IX to force schools to allow students to use the restrooms conforming with how they identify.

President Obama will travel to Dallas Tuesday to pay his respect and assist in the healing process following last week’s killing of five police officers. He will be joined by Vice President Joe Biden, former President George W. Bush, and congressional leaders in a show of unity in the city. But Dallas isn’t so sure Obama can bring the city together, TIME’s Jay Newton-Small reports.

Donald Trump’s old praise for Clinton comes back to bite him. The Democratic hopes of retaking the Senate gets a big boost. And RNC Chairman Reince Priebus says he doesn’t know who Trump will pick as his running-mate.

“Conservatism is temporarily dead. I mean, if you look at it, we have two candidates. Donald Trump is barely a Republican. He’s certainly not a conservative.” — Jeb Bush in an interview with his former press secretary on MSNBC

“No. I haven’t heard who it’s going to be, but I have a pretty good idea of what the field looks like. I think there’s always an element of surprise that could come out of nowhere and shock people.” — RNC Chairman Reince Priebus to TIME on Donald Trump’s vice presidential selection
