President Biden has a clear message for the mounting Democrats expressing doubts regarding his capability to triumph over Donald Trump after his disastrous debate showing: Dare me.

“Challenge me, run against me, if you dare,” Biden declared during an interview with MSNBC on Monday. “Make your announcement, contest me at the convention.”

The comments, expressing frustration as well towards what he viewed as “elite figures in the party” urging him to step aside, were made following a comparably defiant letter he sent to Congressional Democrats on Monday. The two-sheet letter aimed to put an end to speculation regarding his status as the Democratic nominee, asserting, “I steadfastly remain committed to continuing in this contest, to seeing it through to the finish, and to defeating Donald Trump.”

In the extensive message, Biden recognized the worries surrounding his candidacy as “valid apprehensions and concerns about the stakes in this election.” However, he ultimately disregarded the critiques as being influenced by “the media,” “commentators,” “significant contributors,” and “any particular group of individuals.”

“The Democratic Party voters have spoken. They have selected me as the party nominee. Do we now just disregard this process? Do the voters have no say? I refuse to accept that,” Biden penned.

However, both the correspondence and his MSNBC discussion are unlikely to ease Democrats’ concerns. Since the debate, Biden’s several missteps, the discouraging polling indicating nearly half of Democrats believe he should withdraw, Vice President Kamala Harris polling more favorably against Trump than Biden does, and an ABC News interview that hardly instilled confidence, have seemingly weakened Biden’s arguments for persisting with his campaign.

Biden’s message follows reports from the Washington Post about Sen. Mark Warner (D-Va.) planning to convene a meeting with Senate Democrats on Monday to discuss requesting Biden to exit the race. The meeting was subsequently called off. Moreover, at least four House Democratic committee leaders reportedly voiced on a call with Minority Leader Hakeem Jeffries (D-N.Y.) yesterday that Biden should withdraw.
