Executive Orders for virus relief?

He has no legal or constitutional authority to do any of this.

And the last is the prize he's really after. The rest is just a smokescreen.

Trump again threatens executive orders to extend benefits after stimulus talks fall apart

The president described the four proposals he was preparing to take executive action on: 

• Unemployment: A $600 weekly unemployment benefit expired July 31, leaving many out-of-work Americans in a state of financial limbo. It's unclear whether the president may extend the benefit or lower it to a smaller amount, something many Republicans have requested. When asked, Trump would not say the amount he was prepared to offer but said he would be extending the benefits until the end of the year.
• Evictions: A federal moratorium on evictions expired July 24, putting at risk the tenants of more than 12 million rental units nationwide if they miss payments. The president said he wants to extend these protections to ensure renters are not evicted due to the pandemic, but did not say until when. 
• Student loans: Congress also suspended payments on some student loans due to the virus. The provision is set to expire at the end of September. The president said Friday he wanted to extending the deferments "until further notice."
• Payroll tax cut: For months, the president has pushed for a payroll tax cut but has been met with blunt opposition from both parties in both chambers in Congress. Trump said Friday he was preparing to defer payroll taxes until the end of the year, an order he said would be retroactive from July 1.
