Cindy McCain endorsed Democratic presidential nominee Joe Biden on Tuesday night, saying that there is "only one candidate in this race who stands up for our values as a nation, and that is Joe Biden."

Earlier in the evening, Biden announced during a virtual fundraiser that McCain, the widow of Sen. John McCain (R-Ariz.), decided to endorse him after it was reported by multiple news organizations that President Trump called U.S. soldiers who died in combat "losers" and "suckers;" Trump has denied making the comments. John McCain was a U.S. Navy officer and prisoner of war in Vietnam, and three of his children also served in the military.

Over a series of tweets, Cindy McCain explained why she is backing Biden. "My husband John lived by a code: Country first," she said. "We are Republicans, yes, but Americans foremost. There's only one candidate in this race who stands up for our values as a nation, and that is Joe Biden."

McCain went on to say that they "don't always agree on the issues, and I know he and John certainly had some passionate arguments, but he is a good and honest man. He will lead us with dignity. He will be a commander in chief that the finest fighting force in the history of the world can depend on, because he knows what it is like to send a child off to fight." Biden's son Beau, who died of brain cancer in 2015, was a member of the Delaware Army National Guard who served in Iraq. Catherine Garcia

When former President Donald Trump makes his first major return to the public stage at the Conservative Political Action Conference in National Harbor, Maryland, on Sunday, expect his rhetoric to be more reminiscent of his 2016 presidential campaign than his 2020 one, The New York Times' Maggie Haberman reports.

Rather than boast about his own accomplishments during his lone term in the White House, an adviser told the Times, Trump will instead deliver a fierce critique of President Biden's first few weeks in office. Reporting by CBS News' Ed O'Keefe appears to confirm the strategy, suggesting Trump will focus on Biden's immigration policy, school reopening plan, and "identity politics."

That said, Trump will reportedly find time to highlight and defend Operation Warp Speed and the COVID-19 vaccine development that took place under his administration, and he's also expected to bring up the future of the GOP. "There's a 99.99 percent chance" Rep. Liz Cheney (R-Wyo.), who has steadfastly expressed her opposition to Trump in the wake of the Jan. 6 Capitol attack, will be brought up, a source told O'Keefe.

Of course, Trump is known for going off script, so all bets are off. Read more about Trump's return at The New York Times. Tim O'Donnell

President Biden on Saturday praised House Speaker Nancy Pelosi (D-Calif.) and her fellow Democrats who backed in his administration's $1.9 trillion COVID-19 relief bill in the wee hours of the morning. Now, "there's no time to waste" as the package heads to the Senate, Biden added. "If we act now decisively, quickly, and boldly, we can finally get ahead of this virus, we can finally get our economy moving again," he said. "And the people of this country have suffered far too much for too long. We need to relieve that suffering."

The president didn't address the minimum wage issue in his comments, but his call for speed seems to be in line with his previous rhetoric on the matter. Biden has made it clear he'd prefer an item gradually increasing the federal minimum wage to $15 per hour to remain in the bill, but he's also reportedly not interested in rewriting Senate rules or ignoring the parliamentarian who ruled against its inclusion in the package under budget reconciliation, the tool Democrats are using to push the bill through without Republican instruction. Biden has also said he didn't expect the measure to make it through with the rest of the bill. Tim O'Donnell

Sen. Ben Sasse (R-Neb.) didn't exactly pull punches in an interview with Politico, going after congressional Republicans, Democrats, former President Donald Trump, and the Biden administration.

Sasse, who is facing imminent censure from the Nebraska GOP for voting to convict Trump in his second impeachment trial, stands by that vote and says he's not bothered by the action his home state's Republican Party is taking against him, though he did say he thinks it's not "healthy." His comments to Politico seemed to back up his confidence. At one point, when asked about Trump loyalist Rep. Matt Gaetz (R-Fla.), Sasse simply said "that guy is not an adult," and described Congress, generally, as "a bunch of yokels screaming."

Sasse's candor is gutsy, but it's worth noting he's generally well-respected by his Senate colleagues and won re-election handily last year, so he's ensconced in the upper chamber until 2026.

While he's been in the spotlight for his intra-party criticism of late, Sasse did have words for Democrats, as well, per Politico. He said the Biden administration is "cowering" to the opinions of progressive Democrats like Rep. Alexandria Ocasio-Cortez (D-N.Y.) and called the education spending plan in President Biden's COVID-19 relief package as "disastrous." Read more at Politico. Tim O'Donnell

Ali Shamkhani, Iran's top security official, said Saturday that the United States' airstrikes against Iranian-backed militias in eastern Syria earlier this week will rejuvenate the Islamic State in the region, Reuters reports. "The attack on anti-terrorist resistance forces is the beginning of a new round of organized terrorism," an Iranian news agency quoted him as saying during remarks to visiting Iraqi Foreign Minister Fuad Hussein.

Shamkhani reportedly went on to say Tehran "will confront the U.S. plan to revive terrorism" in the Middle East, but didn't elaborate. Later, Iranian Foreign Minister Mohammad Javad Zarif condemned the U.S. strikes as "illegal and a violation of Syria's sovereignty."

The Washington Post, meanwhile, provided an in-depth of analysis of the strikes — which were carried out in response to several rocket attacks against U.S. targets in Iraq — suggesting that whether Iran, which denies involvement in the attacks on U.S. targets, chooses to respond in a way that escalates the already-tense relationship hinges on further developments in the Biden administration's diplomacy.

"The administration’s actions and Europe’s support for U.S. decisions in response to Iran’s regional tests will determine whether Tehran believes it can be more aggressive regionally under Biden," Norman Roule, who previously served as the U.S. intelligence manager for Iran, told the Post. "But if the Iranians go up the escalatory ladder, we have no choice but to do the same in order to protect our forces and our partners."

Still, the sense among experts largely remains that President Biden's Iran strategy will be less bellicose overall than former President Donald Trump's. Read more at Reuters, The New York Post, and The Washington Post. Tim O'Donnell

The House passed President Biden's $1.9 trillion COVID-19 relief package in a 219-212 vote nearly along party lines early Saturday. Two Democrats, Reps. Jared Golden (D-Maine) and Kurt Schrader (D-Ore.) voted against the bill with Republicans, who consider the package too expensive, taking particular opposition to measures like funding for state and local governments.

The legislation, which includes $1,400 direct payments for individuals earning up to $75,000 per year (as well as couples earning a combined $150,000) and extends enhanced unemployment benefits through August, will now head to the Senate, where its contents could change, The New York Times reports.

The bill includes a proposal that would raise the federal minimum wage to $15 per hour by 2025, but Democrats, who narrowly hold the Senate, are using reconciliation, a process that will allow them to pass the bill with a simple majority and avoid Republican obstruction. Reconciliation comes with strict limits on what can be included in a measure, and the Senate's nonpartisan parliamentarian ruled against the wage hike.

Several congressional progressives, who are prioritizing the increase, criticized the decision and called for Senate Democrats to move forward anyway, but the White House said Biden, while disappointed, respects the ruling. Meanwhile, Senate Majority Leader Chuck Schumer (D-N.Y.) and his colleagues are exploring alternatives, including an escalating tax on the payrolls of large corporations whose employees earn less than a certain hourly wage. It's unclear if that will qualify under the rules of reconciliation. Read more at The Associated Press and The New York Times. Tim O'Donnell

A number of Republican lawmakers have reportedly claimed to be unable to attend votes due to the COVID-19 pandemic — even though they're able to appear in person at CPAC.

Several allies of former President Donald Trump in the House of Representatives have "skipped Friday's votes and enlisted their colleagues to vote on their behalf," signing letters declaring they can't themselves attend due to "ongoing public health emergency," yet at the same time, they're expected to speak at the 2021 Conservative Political Action Conference in Orlando, Florida, CNN reported on Friday.

Among these lawmakers is reportedly Rep. Matt Gaetz (R-Fla.), who already spoke to CPAC attendees on Friday. But he's not alone, as CBS News' Rebecca Kaplan reports that a total of 13 House Republicans appearing at CPAC have made proxy voting requests, citing the pandemic as the reason.

Rep. Ted Budd (R-N.C.) was another one of these lawmakers, and his spokesperson told CBS that he "was forced to proxy vote for the first time" after the "Democrats rearranged the House schedule with extremely late notice," adding that "mentioning the pandemic in the letter is the standard language that both parties are required to use to proxy vote." The spokesperson also said that Budd "remains philosophically opposed to proxy voting" despite plans to do so himself.

Notably, Kaplan points out, "among the votes they will miss tonight: one on the COVID relief bill." Brendan Morrow
