WASHINGTON, May 12 (Reuters) - U.S. House Speaker Nancy Pelosi said on Wednesday she was optimistic about the possibility of passing a bipartisan infrastructure bill after a White House meeting with President Joe Biden and other congressional leaders, but sticking points remained.

"I felt optimistic about our ability to pass such a bill. I'm more optimistic now - more optimistic now about being able to do so in a bipartisan way. But we'll see," Pelosi told reporters outside the Capitol. (Reporting by Susan Cornwell; Writing by Makini Brice; Editing by Chris Reese)
