The CPB's funding is relatively minuscule compared to how much Trump is proposing to spend annually on other programs.
At $445.5 million, it's a fraction of discretionary spending and will barely help Trump achieve his wish list.
He also terminates funding for the National Endowment for the Arts and the National Endowment for the Humanities, closer to $300 million.
The Internal Revenue Service notably incurs the wrath of Trump, with a funding reduction of $239 million that accounts for almost half of the $519 million in cuts he wants to make to Treasury's budget.
HUD is slated for reductions, as well. Trump is requesting $40.7 billion from Congress for HUD discretionary funding, a $6.2 billion and 13.2 percent decrease from the current fiscal year.
At the Wednesday briefing Mulvaney contended that 'a lot' of the 'wasteful programs, duplicative programs, programs that simply don’t work' fall under that department's purview.
'We've spent a lot of money on Housing and Urban Development over the last decades without a lot to show for it,' the Cabinet official stated. 'Certainly there are some successes, but there's a lot of programs that simply cannot justify their existence, and that's where we zeroed in.'
Mulvaney said the Department of Transportation's discretionary spending budget is being reduced for the same reason. It's gross budget is being cut by $2.4 billion, or 13 percent.
Among the things funded by the Department of Transportation are Amtrak, the national passenger railroad, and subsidies for airports and interstates.
Trump's budget ends funding for Amtrak’s long distance trains 'which have long been inefficient and incur the vast majority of Amtrak’s operating losses' and refocuses the transportation provider on state-supported and Northeast Corridor train services.
The Department of Justice is getting $27.7 billion for the Department of Justice, $1.1 billion less than it spends currently, which amounts to a 3.8 percent decrease.
At the same time, Trump also wants DOJ to spend $249 million, or 3 percent, more on counterterrorism, counterintelligence and federal law enforcement activities within the FBI.
He also specifies that the agency should spend $9 million more annually than it does presently on background checks for firearms purchases and its data tracking of violent crime in certain cities and communities.
Trump additionally calls on DOJ to spend $175 million more than it does right now to 'target the worst of the worst criminal organizations and drug traffickers in order to address violent crime, gun-related deaths, and the opioid epidemic.'
