The Silicon Valley giant said it made the change last year because it was difficult to keep up with every occasion, but some users questioned the decision.

Goldman Sachs will drop a demand that corporate boards of directors include women and members of minority groups as financial firms backpedal from D.E.I. promises.

President Trump’s executive order is altering scientific exploration across a broad swath of fields, even beyond government agencies, researchers say.

President Trump’s aggressive moves against transgender rights and diversity, equity and inclusion programs have left the Democratic Party casting about for a strategy for how to respond.

The Silicon Valley giant also said it was reviewing other diversity programs and initiatives and would update them if they seemed risky or ineffective.

President Trump has promised a “colorblind and merit-based” society, while also equating diversity with incompetence.

But we’ve underestimated Trump’s political strength many times before.

The government space agency has vocally promoted diversity and inclusion for decades, even during the first Trump administration.

The vice president and transportation secretary claimed that diversity hiring efforts had affected staffing levels among air traffic controllers, but there is no evidence that such efforts played a role in the crash.

Some of those put on leave said they had only a minimal connection to diversity or equity efforts.

Vague federal directives have led to frantic action, and perhaps overreaction, before a Friday deadline.

In a briefing that recalled his most extreme first term remarks, President Trump said without any evidence that diversity initiatives caused the midair collision.

President Trump’s remarks, suggesting without evidence that diversity in hiring and other Biden administration policies somehow caused the disaster, reflected his instinct to immediately frame major events through his political or ideological lens.

As Mark Zuckerberg and other tech titans have embraced President Trump and muffled internal dissent at their companies, their mostly left-leaning employees have objected with subtle acts of defiance.

“Those who do not comply will no longer work here,” Pete Hegseth said in a handwritten notice saying diversity, equity and inclusion initiatives were not welcome at the Pentagon.

For the president’s opponents, it was a week that felt like a decade.

The new defense secretary’s goals run counter to the military’s apolitical tradition and efforts to build a force that mirrors America.

Through a flurry of orders, the new president quickly began driving the country in a different direction on many contentious issues.

Agencies are gripped with uncertainty about how to implement the blizzard of new policies as workers frantically try to assess the impact on their lives.
