After investigating the claim that "the pentagon plans to send 3,000 paratroopers to the Middle East, per the WSJ citing U.S. officials", I can confirm that the Wall Street Journal did report this, and it is true.
For Primary resources, I read the report from the Wall Street Journal. Written and posted on March 24, the WSJ stated that, "A written order to deploy the unit, made up of roughly 3,000 soldiers, is expected in the coming hours, the officials said"(Seligman 2). The Wall Street Journal (WSJ) is considered highly credible due to its rigorous, fact-based reporting on business and finance, strong adherence to journalistic ethics, and its role as a "newspaper of record" with over 39 Pulitzer Prizes.
For Secondary resources, I read the report from the Politico. They said pretty much the same thing that the Wall Street Journal, writing that, "The Pentagon is preparing to deploy about 3,000 troops from the Army’s 82nd Airborne Division to the Middle East, adding to the thousands of Marines already headed to the region to assist with operations in Iran"(Mcleary 1). Politico is generally considered a highly reliable, fact-based source for US and European political news, often rated in the center to lean-left spectrum. Known for breaking insider Washington news, it is regarded as a reputable source for policy-specific reporting.
Potential Biases are probably not a problem here since both political sides are reporting the same thing. Wall Street Journal usually leans right and the Politico often is in the middle or leaning left, and they both reported the same news.
