Many politicians, including Russian President Vladimir Putin, have blamed the current refugee crisis on failed US policies in the Middle East and Africa.
"It would be more than appropriate if the US that so far has not agreed to take on more than merely a few refugees herself, at least pledged money to share in the cost of the refugee crisis," Wagenknecht, a member of the National Committee of the Left party, said.
The US State Department said in August that the United States planned to admit up to 8,000 Syrian refugees in 2016.
Western states have an obligation to provide humanitarian support to hundreds of thousands migrants that they bear responsibility for displacing, a German lawmaker told Sputnik on Thursday.
"It is cynical to question aid for refugees that the West itself has produced," Sahra Wagenknecht argued adding that the current refugee crisis is the product of EU, US "bloody wars" in the Middle East and Africa.
"It is our duty to provide the people who have to flee, with refuge and safety," she said.
