President Joe Biden’s nominee for a federal judgeship in Kansas, Jabari Wamble, requested on Tuesday to have his candidacy pulled from Senate consideration, according to a letter obtained by Reuters.

He left the Biden judicial slate twice in as many weeks, becoming the second. In response to criticism from both sides of the aisle in the Senate, Michael Delaney, a former New Hampshire attorney general who Biden chose for a position on the 1st Circuit U.S. Court of Appeals in Boston, requested to resign last week.

Wamble, the son-in-law of Democratic U.S. Representative Emanuel Cleaver of Missouri, wrote in his letter to Biden that he feels that “it is best” to remain in his current position as a federal prosecutor in Kansas. Wamble did not give detailed reasons for his withdrawal.

Wamble initially was tapped by the Democratic president last year for a seat on the Denver-based 10th U.S. Circuit Court of Appeals, but the nomination expired in the Senate. Biden in February then nominated Wamble instead to serve as a district court judge in Kansas.

The U.S. Constitution gives the Senate the authority to confirm presidential judicial nominations.

Following his withdrawal, White House spokesperson Andrew Bates said Biden is proud to have nominated Wamble, “who has dedicated his life to serving the people of Kansas.”

Politico was the first to report Wamble’s withdrawal. It reported that some aides were concerned that Wamble would receive a “not qualified” rating from the American Bar Association, the lawyers’ group that assesses the qualifications of judicial nominees. No Biden nominee has yet received such a rating.
