“Bernie Sanders will hit the trail for Hillary Clinton on Monday in New Hampshire, in the former Democratic presidential rival’s first event campaigning solo since he announced his endorsement of the former secretary of state in July,” Politico reports.

Sen. Bernie Sanders (I-VT) “is preparing a post-Labor Day blitz of campaign activity… offering what Democratic leaders hope will be a late-in-the-race boost from the liberal icon to the party’s slate of Senate candidates, ” Roll Call reports.

“In addition to attending campaign rallies, Sanders is also expected to raise money for individual candidates — including through the use of his vaunted list of small donors, according to one source close to the senator.”

Sen. Bernie Sanders told CBS News that he may have appeared angry during Hillary Clinton’s presidential nomination acceptance speech but he wasn’t.

Said Sanders: “I always have that look on my face. That’s nothing new. I am not always the smiling kind of guy.”

Washington Post: “As he has wound down his presidential campaign, Sanders has begun to build new organizations and plan for a possible power move if Democrats regain the Senate. He has officially launched Our Revolution, a 501(c)(4) “social welfare” group to build support for liberal policies.”

“It’s the first of a possible trio of Sanders projects. Another will seek to elect like-minded candidates up and down the ballot across the country, and a third possible group might engage in other political activity.”

New York Times: “Revolutions rarely end quietly. It was a lesson that Mr. Sanders seemed to absorb on live national television, with his face betraying surprise and his wagging finger pleading for peace, while his backers shouted over him at a Center City rally on Monday afternoon. ‘We want Bernie!’ they screamed, when he explained his endorsement of Mrs. Clinton.”

“Mr. Sanders appealed for unity, mentioning Mrs. Clinton’s name 15 times in his speech late Monday, and declaring that ‘Hillary Clinton must become the next president of the United States.'”

“But his most loyal supporters were hungry for more combat.”

Politico: “Even Bernie wasn’t Bernie enough to tame Bernie’s revolution.”

“Hundreds of supporters of Bernie Sanders drowned out the Vermont senator with boos Monday as he tried to make the case on the first day of the Democratic National Convention that his fans would need to vote for Hillary Clinton in order to defeat Donald J. Trump.” the New York Times reports.

“At a meeting filled with Sanders delegates, Mr. Sanders tried to convince those gathered that Mr. Trump, the Republican nominee for president, was dangerous and a threat to the Constitution and that, as a result, they needed to vote for Mrs. Clinton… However, his words were immediately met with loud boos which lasted several seconds even as he tried to continue his speech. The senator then paused and waited for people to quiet down. But as he spoke, many continued to sign loudly and shake their heads.”

“Hillary Clinton’s campaign chairman said that as of Monday morning, the campaign had yet to review the speech Sen. Bernard Sanders was scheduled to deliver later on in the evening at the Democratic National Convention, but said he’s confident the speech will be good for the Clinton campaign,” the Washington Times reports.

“It’s not just Republicans that want presumptive Democratic nominee Hillary Clinton in prison,” the Wall Street Journal reports.

“At a lively Sunday march in support of former Democratic presidential candidate Bernie Sanders, chants of ‘lock her up,’ ‘Hillary for Prison’ signs and t-shirts and calls for indictment were common among the most ardent supporters of Mr. Sanders, who arrived in Philadelphia to make their voices heard to the delegates attending the Democratic National Convention.”

“Bernie Sanders’ crusade to shape the Democratic party platform scored a win late Friday night, with the approval of an amendment calling for increasing the federal minimum wage to $15 over time,” the AP reports.

“The fight to get more explicit platform language around wages showed the Vermont senator’s campaign still fighting for the liberal issues that made up his ‘political revolution’ even as his clout fades.”

Washington Post: “At the urging of his wife, Jane Sanders, he has been talking to his inner circle about launching a grass-roots organization to harness the energy of his supporters. Among aides, there is chatter about who might staff such an organization, which might resemble Democracy for America, the group that former Vermont governor Howard Dean launched following his failed 2004 presidential bid.”

The Sanders campaign claims 2.7 million people are on its donor list.

Bernie Sanders said that he will vote for Hillary Clinton for president in November, “the strongest expression of support yet from the Vermont senator for his rival, though he later left the door open that he might change his mind,” CNN reports.
