Republican leader Mitch McConnell, 78, on Thursday revealed he had not been to the White House since August because of the way it has handled Covid-19.
The Kentucky senator said he spoke to the president frequently over the phone but had not visited since 6 August.
Mr McConnell, a polio survivor, contrasted the White House with the Senate, where lawmakers are urged to wear masks and social distance.
His comments come as the White House deals with a Covid-19 outbreak.
Since President Donald Trump’s Covid-19 diagnosis, at least two dozen people in his circle and staff at the White House have reported infections. First Lady Melania Trump, press secretary Kayleigh McEnany and adviser Stephen Miller are among the positive tests.
