UPDATE:

A conservative state lawmaker on Tuesday affirmed he was a heterosexual as he took issue with being touched in the arm by a male colleague.

Rep. Daryl Metcalfe, chairman of the state House State Government Committee, during a meeting castigated ranking Democrat Matt Bradford after the latter touched his arm while addressing him.

In a terse tone, Metcalfe, a Butler County Republican, interrupted Bradford, who was sitting to his left at a conference table, immediately after the seemingly innocent gesture to say:

"I'm a heterosexual. I have a wife. I love my wife. I don't like men as you might so stop touching me all the time. Keep your hands to yourself. If you want to touch somebody, you have people on your side of the aisle that might like it. I don't."

A befuddled Bradford chuckled as he said: "We are officially off the rails."

Other lawmakers can be seen grimacing on a video posted on the state House's YouTube channel.

Ryan W Briggs, a political reporter for @cityandstatepa, in a tweet of the video noted: "Metcalfe also once invited a white nationalist to testify in favor of a bill to make English PA's "official language".

Metcalfe historically has pushed back against LGBT rights and anti-discrimination legislation.

Bradford, a Montgomery County Democrat, explained that his intent was "to beg for your permission for about 30 seconds."

"Then beg. Don't touch," Metcalfe responded tersely to him.

Bradford, who had been trying to make a point about a land-use bill, motioned to postpone until the next meeting. He noted that it would be "wise to keep" to the topic of land-lock easements and roads.

"I'm pretty much without any further comment that could be constructive at this time," Bradford added.
