On Friday, Trump told conservative radio host Rush Limbaugh that Justice Department investigators had “plenty of time to do it.
After Limbaugh read Trump an Axios story on the topic, Trump said he'd be disappointed if Barr had relayed that message to lawmakers.
Still, much of the uptick in tensions between Trump and Barr centers on the Justice Department's handling of the Durham probe.
Even the outlines of the case involving FBI lawyer Kevin Clinesmith, who pleaded guilty in the Durham probe, were already known before he was charged.
Trump aides had banked on the Durham probe being finished before 2020 election to lend credibility to Trump’s claims that his own investigative agencies were working against him.
