Rep. Joaquin Castro (D-Texas), the manager of the Democratic presidential campaign of twin brother Julián Castro, dismissed calls from the Trump campaign and other Republicans Tuesday to delete a tweet identifying some of President Trump’s biggest Texas donors.

Why it matters: Castro posted the names and occupations of 44 Trump donors from San Antonio ahead of the president's planned visit Wednesday to El Paso following Saturday's mass shooting there.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

Context: A racist post attributed to the suspected gunman speaks of "invasion." That word was used in Trump campaign Facebook ads approximately 2,200 times, according to CNN data analysis — a point Castro picked up on as he defended his Monday night tweet.

  • The writer of the anti-immigrant screed said his opinions pre-date Trump's presidency.

The big picture: Anyone who donates over $200 to campaigns must report to the Federal Election Commission.

  • The Washington Examiner notes that while such donors' names can be found via the FEC, some Republicans criticized Castro because his tweet seems to target specific local citizens of his own congressional district.

What he's saying: President Trump Wednesday by tweeting, "I don’t know who Joaquin Castro is other than the lesser brother of a failed presidential candidate (1%) who makes a fool of himself every time he opens his mouth."

"Joaquin is not the man that his brother is, but his brother, according to most, is not much. Keep fighting Joaquin!"

Senate Democrats struck a deal Friday evening to extend unemployment insurance in President Biden's $1.9 trillion COVID-19 relief package after deliberating and halting other action for roughly nine hours, per a Senate aide.

Why it matters: The Senate can now resume voting on other amendments to the broader rescue bill.

A panel appointed by Congress to review security measures at the Capitol is recommending several changes, including mobile fencing and a bigger Capitol police force, to safeguard the area after a riotous mob breached the building on Jan. 6.

Why it matters: Law enforcement officials have warned there could be new plots to attack the area and target lawmakers, including during a speech President Biden is expected to give to a joint session of Congress.

Financial fallout from the Texas deep freeze

Texas has thawed out after an Arctic freeze last month threw the state into a power crisis. But the financial turmoil from power grid shock is just starting to take shape.

Why it matters: In total, electricity companies are billions of dollars short on the post-storm payments they now owe to the state's grid operator. There's no clear path for how they will pay — something being watched closely across the country as extreme weather events become more common.
