President Donald Trump and his attorney Rudy Giuliani both mistakenly made calls to Republican Sen. Mike Lee as deadly riots were unfolding at the US Capitol earlier this week, a spokesman for the senator confirmed to CNN — calls that were intended for another GOP senator the White House was frantically trying to convince to delay the counting of Electoral College votes.

Lee’s spokesman said the calls from Trump and his attorney were intended for Sen. Tommy Tuberville, a newly elected Republican from Alabama.

The effort by the White House to get Tuberville to delay certification of the votes provides insight into the President’s thinking and priorities as a mob of his supporters lay siege to the iconic building. As the President worked to convince Tuberville to delay the process, he and other top White House officials did little to check in on Vice President Mike Pence while he and members of his family were inside the breached Capitol, a source close to the vice president told CNN.

Trump first called the personal cell phone of Lee, a Utah Republican, shortly after 2 p.m. ET. At that time the senators had been evacuated from the Senate floor and were in a temporary holding room, as a pro-Trump mob began breaching the Capitol.
