Minutes after President Trump tweeted that he and Vladimir Putin discussed forming an "impenetrable Cyber Security unit" to guard against election hacking and "many other negative things," Republican Sen. Marco Rubio responded with some tweets of his own:

While reality & pragmatism requires that we engage Vladimir Putin, he will never be a trusted ally or a reliable constructive partner.... Partnering with Putin on a "Cyber Security Unit" is akin to partnering with Assad on a "Chemical Weapons Unit."

Sen Lindsey Graham added on Meet the Press: "It's not the dumbest idea I've ever heard, but it's pretty close."

What to watch: It will be interesting to see how many other Republicans criticize Trump over his willingness to cast aside the election interference and work with Putin. Most would probably rather avoid the topic, but that will be increasingly difficult to do.

Eight Democratic senators on Friday voted against Sen. Bernie Sanders' amendment to ignore a ruling by the Senate parliamentarian and add a $15 minimum wage provision to the $1.9 trillion COVID relief package.

The state of play: The vote was held open for hours on Friday afternoon — even after every senator had voted — due to a standoff in negotiations over the next amendments that the Senate is set to take up.

Easing mask restrictions and on-site dining have increased COVID-19 cases and deaths, according to a study out Friday from the Centers for Disease Control and Prevention.

Why it matters: The report's findings converge with actions from governors this week easing mask mandates and announcing plans to reopen nonessential businesses like restaurants.
