Their stance though is that there is enough money coming in that as long as spending is prioritized, Medicare and SSI will still be covered, along with paying our debts, so long as the admin prioritizes spending. Yellen says we will default on 6/1 or whatever, but hasn't shown anything to prove it, it is simple fear mongering to try and get McCarthy to give in.
As you can see on the treasuries own website, since the start of this fiscal year (October 2022), the US has brough in over 2 trillion, over 4 trillion in a year.

That is still enough for military, SSI, Medicare, and even more. There is money coming in and if they don't want to budge on all these ridiculous programs like the one posted today about teacher promoting trans in Afghanistan. If they want to save money, they can also manage the border better, so we don't have millions and millions of additional people needing various benefits.
It is simple, and this line about "the full faith and credit, we're going to default" is stupid. Before COVID, Trump's budgets were 4.1 and 4.4 trillion, that is covered by the amount of money we currently bringing in. There is no more COVID emergency, Biden does not need 6.7 trillion to spend on a bunch of ridiculous shit that hurts the economy (both with inflation and with pushing us to rely more on China with these ridicllous climate goals)
