Bush said on Thursday that "there's pretty clear evidence that the Russians meddled" in the 2016 US presidential election.
Numerous investigations are under way to determine whether Mr Trump's campaign aided the Kremlin in its efforts.
In 2008 Mr Bush became the first sitting USA president to visit the UAE. After a conversation with Russian President Vladimir Putin in Hanoi, Vietnam, in November, Trump said Putin was "sincere" in his denials. As president-elect, he conceded for the first time previous year that Russian Federation had carried out cyberattacks against the Democratic Party during the election but denied that it was meant to help him win.
On "The Ingraham Angle", Laura Ingraham said Trump should wear this criticism from Bush as a "badge of honor".
