Pennsylvania Sen. Daylin Leach, D-Montgomery, has refused to resign from office as calls for him to leave because of his behavior since sexual misconduct allegations surfaced grew more numerous, Philly.com reported.

In a letter to the Montgomery County Democratic Committee, which called for the three-term state senator to step down, Leach said he “will not resign, under any circumstances” and called the allegations “false accusations of literally the worst kind.”

In a letter from 38 Montgomery County Democratic leaders, including U.S. Rep. Madeleine Dean, D-Montgomery, which became public March 15, Leach was told party members had described him as “lashing out, [showing a] lack of judgement and tone deafness.”

The letter was also signed by Dr. Valerie Arkoosh, the chairwoman of the Montgomery County Board of Supervisors, and District Attorney Kevin Steele.

Leach in his response pointed to his record as a progressive stalwart in the General Assembly since he was first elected as a state representative in 2002.

While party leaders agreed Leach has been “a champion for liberal causes,” they said his conduct in the wake of allegations has “created a divisiveness that threatens party harmony and undermines our cause at a time when we need to be united,” according to reporting on the Pennsylvania Capital-Star website.

In January, reports surfaced that Senate Democrats were investigating allegations that Leach had forced a woman to engage in a sexual act with him in the late 1990s. Leach, who has denied the allegations and sued the accuser for defamation, has not been charged with wrongdoing.

Wolf has previously called on Leach to resign.
