Biden's 1st 100 days live updates: Senate passes COVID relief bill along party lines

Biden thanked and congratulated the National Aeronautics and Space Administration (NASA) team involved in the successful landing of the Perseverance rover on Mars in a video call Thursday evening.

The president sat at the desk facing a large monitor, another one over his shoulder. He took no questions, but spoke at length with the NASA team, thanking them for all their work and everything they’ve done to inspire and bring hope to the nation.

"You feel like you’re living a dream. You’ve created a dream for millions of young kids and Americans. You all did this," Biden said.

He said the team had restored "a dose of confidence in the American people" and that it was a result of their belief in "science and hard work."

"It’s bigger than landing on Mars," the president said. "It’s about the American spirit. And you did it. It matters. Democracies have to show how they can run better than autocracies. I can’t tell you how much I believe historians will write about what you did at the moment you did it. You should take great pride in it. We can land on Mars. Beat a pandemic, with science. God only knows what will come from this. I just wanted to thank you. Tell you I am so proud of you. Not a thing we cannot do when we set our minds to it."

NASA's Perseverance rover successfully touched down on Mars in late February. It was one of the agency's most ambitious deep-space missions designed to search for signs of ancient life on the planet.

Present were members of the team including Michael Watkins, director of the Jet Propulsion Laboratory, Swati Mohan, guidance and controls operations lead of Mars 2020, Luis Dominguez, deputy electrical lead of Mars 2020, Matt Smith, spacecraft systems engineer and Researcher at the Jet Propulsion Laboratory, and Annalise Sundberg, Assembly, Test, & Launch Operations systems engineer at the Jet Propulsion Laboratory. Also on the call were more than 6,080 employees of the Jet Propulsion Laboratory from across the country.

A Capitol security review will recommend adding roughly 1,000 new Capitol Police officers to the force and improving infrastructure around the Capitol Hill complex, according to an executive summary obtained by ABC News. 

The draft report -- shared with congressional leaders and relevant committees -- recommends replacing the temporary, razor wire-topped fencing around the House and Senate office buildings with mobile and retractable fencing that could still "enable an open campus," absent any threats. It also recommends empowering the Capitol Police chief to request assistance from federal law enforcement and the D.C. National Guard in an emergency, to avoid the extensive delays that plagued the response to the Jan. 6 riot. 

House Speaker Nancy Pelosi told reporters Thursday that lawmakers will review the draft and "hear what the security folks have to say” before proposing any changes to the Capitol's security apparatus. 

The review, details of which were first reported by CNN, also recommends establishing a permanent quick reaction force to be on standby in Washington to supplement Capitol Police and local law enforcement when needed, suggests that Capitol Police maintain civil disobedience units when Congress is in session and consider reestablishing a mounted unit that could help patrol the Capitol grounds.

The Senate is taking up the COVID relief bill after Vice President Kamala Harris came to the floor to break the tie.

Republicans who claim the bill is massive and won't address issues related to the pandemic have set the stage for a lengthy series of procedural measures designed to slow down momentum.

Democrats, however, are projecting that they will hold together and vote unanimously in favor of the aid after Biden made concessions to appease the moderates.

"We're going to just keep drinking coffee and getting this thing done," Sen. Debbie Stabenow, D-Mich., said.

Biden, Harris, Secretary of Transportation Pete Buttigieg and bipartisan lawmakers on the House Transportation and Infrastructure Committee including committee chair Rep. Peter DeFazio, D-Ore., and ranking member Rep. Sam Graves, R-Mo., were meeting Thursday in the Oval Office about a major infrastructure reform bill.

Passing the legislation, which could be Biden's moonshot, was something his predecessors, former presidents Barack Obama and Donald Trump, set out to accomplish but did not.

"It not only creates jobs but it makes us a hell of a lot more competitive around the world if we have the best infrastructure in the world," Biden said.

The meeting comes the same week that the American Society of Civil Engineers gave American infrastructure a C- score on its 2021 Infrastructure Report Card, which is up from a D+ in 2017.
