Sen. Kamala Harris (D-Calif.) had an up-and-down weekend.

Her Democratic presidential campaign received a helpful endorsement, but reports of internal strife led to questions about the future of her White House bid. And while she reportedly received some hearty support during her speech at the California Democratic convention on Saturday, some strategists in her home state think the clock is ticking for the senator, who was once considered a serious contender for the nomination, Politico reports.

"Of course she should get out," said one leading Democratic strategist who declined to speak on the record. "But who's gonna tell her?"

Harris is struggling in the polls, but has reportedly told California insiders that she's not planning on dropping out of the race at least until after the Iowa caucus. But there are fears that even that could be too late and harm her reputation in the long run. "It's not happening," a leading grassroots organizer told Politico on the condition of anonymity. "She has her chance [to leave the race] ... she should take it."

One person who isn't buying the rumors of Harris' demise is California Gov. Gavin Newsom (D), who felt no need to speak anonymously and said he thinks there's still time and space for the senator to get back in the race. "She's too talented to be dismissed — she's too capable," he said. Read more at Politico. Tim O'Donnell

President Trump has a penchant for tagging his political opponents with simple, but biting nicknames. The one he chose for his presumptive Democratic presidential challenger, former Vice President Joe Biden, doesn't seem to have landed like those in the past, however, Axios reports.

It's well-known Trump refers to Biden as "sleepy Joe," but so far, at least judging by Google search trends, voters apparently don't associate the moniker with Biden all that much. Trump dubbed his 2016 opponent, Hillary Clinton, as "crooked" Hillary, which prompted far more searches than "sleepy Joe." As analysts noted, there are likely several reasons for this. Regardless, it could be a small, but telling data point that shows Trump's patented insults may not have the same affect in 2020 now that the novelty has worn off.

Of course, it could just be that "sleepy" isn't particularly evocative, which is perhaps why the Trump campaign has recently starting trying out "corrupt Joe Biden." Read more at Axios. Tim O'Donnell

May and June unexpectedly produced strong jobs reports. The unemployment rate, while alarming, is much lower than it was in April after the first surge in coronavirus cases and appeared to skate around economists' most pessimistic projections. But Mark Zandi, the chief economist at Moody's Analytics, told CBS News' Margaret Brennan on Sunday that things are likely to take a turn for the worse.

Zandi said the return of millions of jobs over the last two months is at least in part the result of states reopening businesses too soon amid the pandemic. Now that infections are climbing in several states that mostly avoided the worst back in March and April, those places are "pulling back" their reopening efforts, which hasn't shown up in the data yet. "That's coming down the road," he said, predicting that June's progress is in the rearview mirror.

The most recent spike in states that play a driving role in the national economy, like Texas, California, and Florida, is "very disconcerting," Zandi said, adding that "the prospects of going back into a recession are pretty high." Tim O'Donnell

Susan Rice, who has previously served as both the United States Ambassador to the United Nations and former President Barack Obama's national security adviser, is "very much in the mix" to be former Vice President Joe Biden's running mate as he tries to unseat President Trump in the 2020 election, a source close to the Biden campaign told The Hill.

Rice doesn't get as much attention as two other candidates for the job, Sens. Kamala Harris (D-Calif.) and Elizabeth Warren (D-Mass.), but she does appear to have a leg up on the lawmakers in one area. "I know [Biden and Rice] have a good relationship — perhaps the best relationship of anyone on the list," the same source said. "They've known each other for years, they've worked alongside each other and she's been tested in a way that a lot of folks on the list just haven't been."

Biden has gone on the record saying he wants his potential vice president to be someone who is "simpatico." That is, someone who agrees with him on both "philosophy of government" and "the systemic things you want to change." Rice seems to fit the bill in that case — a former Obama administration official said she "makes perfect sense."

On Sunday Rice continued to play it cool, telling NBC's Andrea Mitchell, "let's not get ahead of ourselves" when asked about the possibility, but she did address some skepticism about her lack of experience running for office by noting that not only did she serve in government for years, she's worked on multiple campaigns. Whether she's Biden's running mate or a "door knocker," though, Rice said she'll do whatever she can to get Biden elected. Tim O'Donnell

President Trump on Saturday sounded optimistic about the United States' ability to emerge from the coronavirus pandemic sooner rather than later. During an Independence Day speech at the White House, the president predicted a vaccine would be available "long before the end of the year," and also downplayed the threat of the virus, describing 99 percent of COVID-19 cases as "harmless." Those words seemed to place Food and Drug Administration Commissioner Stephen Hahn in a tough spot.

On Sunday, Hahn was diplomatic when asked by ABC News' Martha Raddatz and CNN's Dana Bash to respond to Trump's comments. He didn't directly refute his boss, but he did say "we don't want to have any" cases or deaths from the virus and urged people to follow guidelines from the Centers for Disease Control and Prevention so they can protect vulnerable people. "People need to take it seriously," Hahn said.

As for the vaccine, Hahn assured viewers that the FDA is moving at a rapid pace, but because the agency is committed to making sure any potential vaccine or treatment is safe for widespread public use, he can't make any predictions about when one would become available. Tim O'Donnell

President Trump's re-election may depend on flipping blue states like Minnesota, Nevada, New Mexico, and New Hampshire, people close to or involved with his campaign told Politico.

The campaign has always remained determined to win over those four states, but they were once considered luxury add-ons. But now campaign aides, senior administration officials, and GOP donors are reportedly privately acknowledging that it's just as plausible Trump loses Michigan, Wisconsin, and Pennsylvania to the presumptive Democratic nominee, former Vice President Joe Biden, which would put Trump under the 270 electoral vote threshold required to win if everything else played out as it did in 2016. Wisconsin, in particular, is looking quite tenuous for Trump, NBC News reports. "Independents are walking away from Trump," said Charlie Sykes, a former conservative radio talk show host in Wisconsin. "That's a big deal."

One of Trump's advisers told Politico that even if the campaign loses two of the Rust Belt states, picking up New Hampshire and one of New Mexico and Nevada would help clinch a second-straight victory. But at the moment, polls show Biden ahead in all three of those states, as well as Minnesota, long considered another possible Trump pickup.

While Trump's team is coming up with ways to make sure they can get to 270, the Biden campaign says it's "playing offense" and looking to "get in front of a large volume" of voters who supported former President Barack Obama in 2012 and Trump in 2016.

Despite China's assurances that freedom of speech would be protected in Hong Kong under the recently-passed national security law, there are already signs of censorship.

Online records show books written by prominent Hong Kong pro-democracy activists like Joshua Wong or pro-democracy Tanya Chan are no longer available in the city's public libraries. Hong Kong's Leisure and Cultural Services Department said Sunday it will "review whether certain books that violate the stipulations" of the law, which aims to root out secessionist activity, subversion, terrorism, and collusion with foreign forces following several months of anti-government, pro-democracy protests in the city. It's not clear how many books are under review, and Reuters notes two works by Chinese political dissident and Nobel Peace Prize winner Liu Xiaobo were still available.

While China has maintained the legislation will only target a "very small minority" of "troublemakers," critics believe it will lead to widespread censorship and severely limit Hong Kong's autonomy. The removal of books from the library isn't the only example of those fears coming true — the day the law came into effect, a man was arrested for carrying a Hong Kong independence flag and on Friday the government declared the slogan "Liberate Hong Kong, revolution of our times" illegal.
