While Tyson didn’t mention the president by name on Sunday, there was no doubt he was referring to Trump’s proposed cuts to science, the arts, health, education and more in a series of tweets:

The fastest way to Make a America Weak Again: Cut science funds to our agencies that support it.

The fastest way to Make America Sick Again: Cut funding to the National Institutes of Health

The fastest way to thwart Earth's life-support systems for us all: Turn EPA into EDA — the Environmental Destruction Agency.

The fastest way to melt glaciers & flood the World's coastal cities: Ignore scientists and do nothing to stem the rise of CO2

We can all imagine a land that provides no support for Art. But is that a place you’d want to Live? To Visit? To Play?

The very best way to support and feed your delusions: Surround yourself with people whose world views match yours exactly.

We all want to Make America Great Again. But that won't happen until we first Make America Smart Again.

Last week, Tyson said he was holding back on criticism until he saw some actual policy proposals. With the budget now public, it looks like Tyson is making good on his word.
