Democrats said Republicans need to first unite behind a proposal. "It's time for them to put out a budget," White House spokesperson Karine Jean-Pierre said in a statement.
Biden, a Democrat, has insisted that Republicans who control
the House instead raise the $31.4 trillion debt ceiling without
conditions and produce a fiscal 2024 spending plan before he
will engage in talks about spending.
"Your position - if maintained - could prevent America from
meeting its obligations and hold dire ramifications for the
entire nation," McCarthy said in the letter.
The political standoff, which has taken hold since Biden and
McCarthy held an initial meeting in early February, has raised
concerns in the financial markets about a possible U.S. debt
default that could cripple the economy.
Republicans have sought to blame Biden, but only Congress
has the authority to raise the debt ceiling.
"The only thing missing is a real plan," Democratic Senate
Majority Leader Chuck Schumer said in a floor speech.
