Latest speech from Austin has only these mentions of Abrams & Leopards:
'I’m also pleased to announce that the M1 Abrams tanks that the United States had previously committed to will be entering Ukraine soon. [...]
I’m grateful to many friends here today—including Denmark, Estonia, Germany, Luxembourg, the Netherlands, and Poland—for stepping up to lead coalitions. These coalitions are tackling specific capabilities, such as Leopard tanks, F-16 training, and Information Technology.' - https://www.defense.gov/News/Speeches/Speech/Article/3529842/opening-remarks-by-secretary-of-defense-lloyd-j-austin-iii-at-the-15th-ukraine/
And only the usual reference to a supposed 'rules-based international order'. Plenty more delusional / lying rubbish in there, mind.
