US President Donald Trump is standing by his personal lawyer amid reports that federal prosecutors are looking into Rudy Giuliani for possible lobbying violations.
Trump tweeted on Saturday that Giuliani is the victim of what the president calls "a one sided Witch Hunt".
The New York Times reported on Friday, citing two anonymous sources familiar with the inquiry, that the investigation is linked to Giuliani's efforts to undermine the former the US ambassador to Ukraine.
However, some aides and advisers to the president tell The Associated Press they wish he would cut ties with Giuliani.
Giuliani's efforts on behalf of Trump led Giuliani to Ukraine, which now entangles the former federal prosecutor and mayor in legal jeopardy and is central to the danger threatening the presidency he laboured to protect.
