NEED TO KNOW

Impeachment Trial Begins

The Senate voted 56-44 to proceed with the trial of former President Donald Trump yesterday, following four hours of debate over the constitutionality of the process. Republican Sens. Susan Collins (ME), Lisa Murkowski (AK), Ben Sasse (NE), Pat Toomey (PA), Mitt Romney (UT), and Bill Cassidy (LA) joined all 50 Democrats in supporting the procedural vote. 

The defense\'s primary arguments are that the process is unconstitutional, Trump didn\'t drive the crowd to insurrection during a Jan. 6 speech, and the trial violates the former president\'s First Amendment rights. See the pretrial brief here.

The Constitution does not specify whether an official can be tried after leaving office, and there is no legal consensus—though many experts have noted such an interpretation hypothetically means a president has near-free rein near the end of their term. As a precedent, Secretary of War William Belknap was impeached and tried after resigning in 1876 (the Senate fell short of the two-thirds needed to convict).  

Democratic impeachment managers appear likely to rely on video evidence from the Jan. 6 storming of the US Capitol. Their opening argument yesterday included a 13-minute montage (warning: language) with some new footage.

The trial will move on to 16 hours of arguments per side. Democrats have retained the option to hold a vote to call witnesses; in the absence of any new testimony, the trial is expected to conclude early next week.

Editor\'s note: Yesterday, we said former President Trump was the first to be impeached after leaving office—the House impeaches (which occurred Jan. 13), while the Senate holds a trial.

Martian Madness

The United Arab Emirates\' Hope space probe successfully entered the Martian orbit yesterday, the first of three separate missions from different countries expected to arrive before the end of next week. The achievement makes the UAE the fifth space agency—and first Arab nation—to successfully reach the red planet, behind the US, Soviet Union, European Union, and India.

A notoriously difficult feat of engineering, placing the spacecraft in orbit required a precisely timed 27-minute deceleration from 75,000 mph to 11,000 mph; mission control then had to wait for another (very tense) 11 minutes for a success signal to reach Earth. The probe will spend the next two years measuring the Martian atmosphere at varying elevations.  

China\'s Tianwen-1 rover arrives tomorrow (see a photo from its approach). NASA\'s highly anticipated Perseverance rover—which will look for past signs of microbial life—lands next week. 

Florida Water Hack

Officials are searching for a hacker accused of taking control of a water treatment facility\'s computer system in Oldsmar, Florida, in an effort to poison the town\'s water supply. The suspect attempted to elevate the amount of sodium hydroxide—also known as lye—in the water to dangerous levels Friday. The chemical can cause burns at high concentrations and may be fatal if ingested. 

The effort was reportedly thwarted when a plant operator noticed two instances of the system being commandeered and was able to correct the change.

The incident is the latest warning that critical infrastructure in the US, particularly under local jurisdiction, is vulnerable to cyberattacks. There are no suspects identified as of this morning; investigators are looking at whether the attack was US-based or international. It is unknown why the town of 15,000 was targeted. Officials say the water system is no longer capable of remote access.
