Iranian President Hassan Rouhani on Saturday affirmed Tehran will continue to cease complying with certain aspects of the 2015 nuclear deal if other signatories do not soon start showing "positive signals." He did not provide many specifics, including what, exactly, those positive signals would be. Other signatories include China, Russia, the United Kingdom, France, and Germany — the U.S. withdrew from the pact last year.

Tehran announced in May it would start enriching uranium again unless other world powers ignored U.S. sanctions within 60 days. The European signatories have said they want to save the nuclear pact, but several European companies have complied with Washington's sanctions after facing financial pressure from the U.S.

"Obviously Iran cannot stick to this agreement unilaterally," Rouhani said at a meeting with Russian, Chinese, and other Asian leaders in Tajikistan.

Rouhani did not mention the recent attacks on two oil tankers in the Gulf of Oman earlier this week, amid speculation that Iran was behind the act. Tehran has denounced any such accusations, calling them "ridiculous" and "dangerous." Tim O'Donnell

Former Vice President Joe Biden, the presumptive Democratic nominee, is reportedly taking a cautious approach to states like Texas, but two new polls released Sunday will seemingly bolster the hopes of his supporters who want him to go all in.

A survey conducted by The Dallas Morning News and the University of Texas at Tyler found Biden to have a five-point lead over President Trump, with UT-Tyler political scientist Kenneth Bryant Jr. describing the jump as a result of Trump losing with independents and "weak partisans."

A CBS News poll conducted by YouGov indicated the loss of support likely has to do with how voters feel about Trump's coronavirus response. The CBS Poll isn't quite so high on Biden's chances in Texas — Trump holds a one-point advantage over his challenger — but it does show the former vice president is in the race there, as well as two other key Sun Belt states, Florida and Arizona.

All three states are struggling with coronavirus surges, and voters aren't happy about it. The results show 69 percent of Arizonans, 65 percent of Floridians, and 62 percent of Texans think efforts to contain the virus are going poorly. About six in 10 voters in all three states believe their economies opened too early. In Florida 68 percent think that was because of pressure from the Trump administration. The number is a little lower in Texas at 61 percent, but 70 percent of Arizonans think their government was under pressure from the White House.

The Dallas Morning News poll was conducted by between June 29 and July 7, sampling 898 registered Texas voters. The margin of error was 2.24 percent. CBS News and YouGov conducted three separate polls in Florida, Texas, and Arizona between July 7-10. The margin of error was 3.5, 3.3, and 3.8, respectively. Tim O'Donnell

Florida keeps breaking records it never wanted to break.

On Sunday, the state reported more than 15,000 new coronavirus cases, shattering its previous record of 11,336 set on Thursday.

If Florida were a country only the United States, Brazil, and India would have recorded more new infections over that same span, Reuters reports. Per Reuters, no European country recorded a daily number that high during the height of the pandemic there, while Florida also broke New York state's previous record of 12,847 new cases on April 10 when it was the epicenter of the outbreak in the United States.

One slight silver lining is that the positivity rate dropped slightly in Florida thanks to an increase in testing even though the number of positive results increased.

Florida and has faced scrutiny during the pandemic, with critics believing the state reopened parts of its economy too quickly. Read more at Reuters. Tim O'Donnell

The United States has been experiencing a major surge in coronavirus cases in recent weeks, primarily in the South and West, but deaths continued to fall nationwide despite the explosion. Scientists, however, had been warning that wouldn't last, as fatalities are a lagging factor in this pandemic.

Now, deaths are indeed increasing, although the rate is still well below the heights in April when New York City was in the middle of the worst of its battle with the virus, The Associated Press reports. Still, California, Arizona, Florida, Illinois, and South Carolina have seen sizable rises in fatalities. (New Jersey has, as well, although AP notes this is at least partly attributable to its less frequent reporting on probable deaths.).

The rolling average for daily reported deaths in the country was up to 664 on July 10, an increase from 578 two weeks ago, a Johns Hopkins University tally shows, and the increase over the past few days is much sharper than the decline had been over the last few weeks. Tim O'Donnell

The Federal Reserve and Treasury Department disagreed over how easy loan terms should be while crafting their $600 billion Main Street Lending Program meant to help support businesses through the early stages of the coronavirus pandemic, The Wall Street Journal reports.

The differing viewpoints slowed the program's start before it opened this past week, current and former government officials told the Journal. While the disagreements were over narrow design issues, the Journal notes it reflects a broader difference in approach by the two agencies.

Ultimately, the Treasury Department has been more cautious about the lending terms, preferring the government take on less risk, while the Fed supports more generous terms for borrowers.

Some Fed officials have reportedly privately expressed frustration over the situation, but on the record both sides played it cool. "Would the program be exactly the way I would have designed it, or exactly the way someone else would have designed it? No, but we all need to work together, and we have worked together quite effectively," said Boston Fed President Eric Rosengren.

Treasury Secretary Steven Mnuchin doesn't even consider the holdup the result of disagreements. Instead, he said the two sides simpyl got into "even more levels of complexity that required considerable thought." Read more at The Wall Street Journal. Tim O'Donnell

Iranian investigators on Saturday released a report blaming a misaligned missile battery and miscommunication between soldiers and their commanders for the Islamic Revolutionary Guard Corps shooting down a Ukrainian International Airlines passenger jet in January, killing 176 people. Iranian government and military authorities initially denied responsibility for the incident, but eventually admitted the IRGC's fatal error, sparking anti-government protests.

At the time, Iranian troops were on high alert for a U.S. response to an Iranian ballistic missile attack targeting U.S. soldiers at an Iraqi army base, a retaliatory act following a U.S. drone strike that killed Iranian Gen. Qassem Soleimani. The report found that while using a relocated surface-to-air missile battery that was not properly reoriented, the operator received erroneous information on the plane's trajectory, mistaking it for a missile, although "human error" received the ultimate blame — the report said the operator still should have been able to identify the aircraft "which was flying at a normal altitude and trajectory."

After the misidentification, those manning the missile battery were unable to communicate with their command center and fired twice without getting approval. "If each had not arisen, the aircraft would not have been targeted," the report said. Read more at The Associated Press and Middle East Eye. Tim O'Donnell

Several presidents, including George H.W. Bush and Bill Clinton, were criticized for pardoning political allies during their tenures in the Oval Office, The New York Times reports, but President Trump's critics think the commutation of Roger Stone's prison sentence stands out.

In 1992, Bush pardoned former Defense Secretary Caspar Weinberger after Lawrence Walsh, the independent counsel investigating the Iran-Contra affair, filed a new indictment against Weinberger that made public notes contradicting Bush's assertion he was not aware at the time of the arms-for-hostages aspect of the weapons deal. Clinton, meanwhile, stoked bipartisan furor when he pardoned financier Marc Rich in the final hours of his presidency in 2001. Rich fled the country to avoid charges of evading $48 million in taxes, but obtained his clemency after his ex-wife, Denise Rich, contributed money to Clinton's presidential library.

Jack Goldsmith, a Harvard law professor who served as a high-ranking Justice Department official during George W. Bush's presidency, said those pardons are parallels to Stone's commutation, but Goldsmith believes Trump's larger pattern of bailing out his friends and allies puts him in his own league. Goldsmith determined that, out of Trump's 36 pardons or commutations, the act advanced Trump's political goals or benefited someone to whom he had a personal connection 31 times. "This has happened before in a way," Goldsmith said. "But there has been nothing like Trump from a systematic perspective."

The New Yorker's Jeffrey Toobin is also troubled by that pattern, but even among those 36 cases, he thinks Stone's is the most concerning. As Toobin writes, even former President Richard Nixon, the modern era's commander-in-chief most synonymous with political corruption, understood granting clemency to someone who could potentially testify against him was "just too hot."
