Rep. Daniel Patterson has taken to Twitter to deny allegations of abuse from his now ex-girlfriend:

Allegations are lies from person w bad mental problems & violent criminal history trying to blackmail me. I will not resign.

Meanwhile, Patterson's support at the Capitol continues to collapse as Democrats in the Arizona Senate, including seatmate Linda Lopez, have called on him to step down:

Senate Democratic Leader David Schapira, Assistant Democratic Leader Leah Landrum Taylor and Senator Linda Lopez (D-29) released the following statement urging Representative Daniel Patterson (D-29) to resign.

“This Legislature expects that its members adhere to standards of conduct, which the Senate Ethics Committee upheld just last month. If any legislator, regardless of party, cannot adhere to these standards they must, at the very least, respect the constituents who elected them by resigning. With so many problems facing our state right now, Arizonans cannot afford to have their elected officials be focused on anything but finding solutions.”
