Only thing I can find regarding pelosi being in hawaii is from last year, december 2018. Couldn't even locate this tweet from richard meyer. ctr+f on his twitter had no hits for hawaii and 1 for pelosi regarding impeachment
But Pelosi did not spend christmas in Hawaii.

I can't find anything saying that she is there besides random twitter posts that don't have sauce saying she's there
