AIR Force Two was forced to return due to a "technical issue" just 30 minutes after Kamala Harris took off on Sunday for her first international trip as vice president. The technical issue is said to have involved “no major safety concerns.”The vice president gave reporters a thumbs-up as she arrived safely back on the tarmac. There are no major safety concerns,'' Harris's spokesperson Symone Sanders told reporters traveling with the vice president. The Vice President will travel to Mexico City on Tuesday. Republicans, especially local lawmakers living along the border, have called on Harris to visit the area while she is in Mexico.
