There's huge drama in the American elections, with one of the men in the running to be the next president saying he's putting his campaign on hold.
John McCain says he's suspending his campaign to return to Washington to deal with the country's money problems.
Meanwhile, in a TV speech, President George Bush warned people in America that the entire economy was in danger.
He's invited both of the presidential candidates to the White House to talk about America's financial difficulties.
With just over a month to go until the elections, the two rivals are due to go head-to-head in a TV debate on Friday.
Mr McCain, the Republican candidate, wants the debate to be put off until a later date, because of the country's money problems.

But the Democratic candidate, Mr Obama, says it should go ahead.
He says it's important for people in America to hear how both candidates plan to sort everything out, if they become president.
