The United States has so far been Ukraine's largest donor in the war against Russia, and Ukraine is dependent on the aid packages from the West.
"It is the courage of the Ukrainians and your support that will determine the outcome on the battlefield," Ukrainian President Volodymyr Zelenskyy said during a press briefing earlier in October.
But after Wednesday night's election of Mike Johnson as Speaker, there is growing concern that there will be no help from the United States. There is political disagreement in the United States about the country's support for Ukraine.
How the new Speaker will affect the war in Ukraine
According to SVT's US correspondent Fouad Youcefi, the election of Mike Johnson was "very bad news for Ukraine".
The Speaker of the United States has a very significant role and is usually seen as the most important power holder in Congress as the Senate is less controlled from the top.
The Speaker has the power to autocratically control the agenda of the House of Representatives in order to implement his or her political agenda – and to decide what rules are to be followed in individual cases. And Johnson's support is not self-evident.
- Mike Johnson has voted no several times when discussing continued support for Ukraine, says Youcefi in SVT's Aktuellt.
Elin Jönsson: Ukraine received the news with great concern
SVT's Ukraine correspondent Elin Jönsson, who is on the ground in Ukraine, describes the concern after the election of the Speaker as great.
"When we meet soldiers here, they know exactly which weapons come from which country, and how much you get," she says.
She also says that many people follow American domestic politics "very closely".
"Above all, you know what happens if the support is not forthcoming," she says.
