WASHINGTON — An emerging $900 billion COVID-19 aid package from a bipartisan group of lawmakers all but collapsed Thursday after Senate Majority Leader Mitch McConnell said Republican senators won’t support $160 billion in state and local funds as part of a potential trade-off in the deal.

McConnell’s staff conveyed to top negotiators that the GOP leader sees no path to an agreement on a key aspect of the lawmakers’ existing proposal — a slimmed-down version of the liability shield he is seeking for companies and organizations facing potential COVID-19 lawsuits — in exchange for the state and local funds that Democrats want.

The GOP leader criticized “controversial state bailouts” during a speech in the Senate, as he insists on a more targeted aid package.

The hardened stance from McConnell, who does not appear to have enough votes from his Republican majority for a far-reaching compromise, creates a new stalemate over the $900-billion-plus package, despite days of toiling by a bipartisan group of lawmakers to strike compromise.
