During a visit to the US-Mexico border wall, President Trump autographed one of the posts of the wall with a Sharpie.

Video and online photos show Trump signing a section of the wall in Otay Mesa, California, following a press conference there.

“At invitation of the construction personnel, Pres Trump pulls out a Sharpie and signs one of the posts of the border wall,” CBS News White House correspondent Mark Knoller said in a tweet.

“Other officials follow suit.”

Trump is hyping the completion of some sections of border wall during his 2020 re-election campaign.
