AstraZeneca announced Sunday a comprehensive review has found "no evidence" that its COVID-19 vaccine causes an increased risk of blood clots.

Why it matters: Authorities in Ireland, the Netherlands, Denmark, Norway and Iceland have paused administering the vaccine because of clotting concerns, per Reuters.

  • Austria suspended its AstraZeneca rollout while authorities investigated the death of one person who had received a dose, per Reuters.

What they're saying: AstraZeneca said in a statement that it had conducted a "careful review of all available safety data of more than 17 million people vaccinated in the European Union" and the U.K.

  • It showed "no evidence of an increased risk of pulmonary embolism, deep vein thrombosis (DVT) or thrombocytopenia, in any defined age group, gender, batch or in any particular country," the company said.
  • There have been 15 events of DVT and 22 events of pulmonary embolism reported across this region among those given the vaccine, per AstraZeneca.
  • "This is much lower than would be expected to occur naturally in a general population of this size and is similar across other licensed COVID-19 vaccines," it noted.
"Furthermore, in clinical trials, even though the number of thrombotic events was small, these were lower in the vaccinated group. There has also been no evidence of increased bleeding in over 60,000 participants enrolled."

Of note: European Medicines Agency is investigating incidents of blood clots concerning AstraZeneca's coronavirus vaccine, developed with Oxford University.

  • But the agency has said the benefits "currently still outweigh risks."

The big picture: AstraZeneca has been authorized for use in the EU and also by the World Health Organization, paving the way for the COVAX initiative that's designed to ensure that every country has access to COVID-19 vaccines.

  • The company is expected to file for U.S. approval later this month or early April, according to Reuters.

President Trump filed a lawsuit Monday seeking to block the National Archives from releasing White House records to the House select committee investigating the Jan. 6 Capitol insurrection, citing executive privilege.

Why it matters: It's the latest escalation in Trump's campaign to disrupt the committee's sweeping probe into the circumstances surrounding Jan. 6, including his actions and communications leading up to the Capitol attack.

Obama says Powell exemplified what America "can and should be"

Former President Obama called Colin Powell an "exemplary soldier and an exemplary patriot" in a statement honoring the former general following his death from COVID-19 complications on Monday.

Why it matters: Powell, the first Black U.S. secretary of state, was known as a Republican but played a critical role in helping Obama get elected in 2008.

Justice Department asks Supreme Court to block Texas abortion ban

The Justice Department on Monday asked the Supreme Court to temporarily block Texas' near-total ban on abortions while federal courts consider its constitutionality.

The big picture: The court last month allowed the ban to take effect, rejecting an emergency application by abortion-rights groups. The law bars the procedure after cardiac activity is detected, as early as six weeks into pregnancy.
