WASHINGTON (Reuters) - The U.S. House of Representatives will consider additional aid for Ukraine as soon as next week, Speaker Nancy Pelosi said on Thursday, after President Joe Biden announced plans to ask Congress for more assistance for Kyiv.

       "We'll learn about that in the next day or so, to be taken up as soon as we can next week," she told reporters at a photo opportunity with Ukrainian Prime Minister Denys Shmyhal before a bipartisan meeting about the needs of Ukraine.

       Biden, who announced an additional $800 million in military assistance for Ukraine on Thursday, said the amount of additional help in the upcoming request was still being decided.

       Shmyhal earlier attended meetings at the White House, including with Biden and members of his cabinet.
