President Donald Trump's administration ordered a temporary freeze on federal grants and loans, sparking widespread confusion among Arizona companies, agencies, and other recipients of federal dollars.

The order is temporarily on ice, but uncertainty swirls around which programs would and wouldn't be hit by the federal aid freeze.

Supporters of climate, infrastructure, mortgage, tech, health, veterans' and other projects expressed alarm as tens of thousands of programs appeared possibly at risk.

Organizations that depend on federal aid are bracing to see how the Trump administration will proceed after reversing course on its sweeping funding freeze.
