June 30 (Reuters) - The U.S. House Judiciary Committee

on Monday subpoenaed a former Pfizer executive after he

declined to voluntarily comply with the committee's oversight

into whether the company intentionally delayed clinical trial

results of its COVID-19 vaccine until after the 2020

presidential election.

The committee subpoenaed Philip Dormitzer, the company's

former global head of vaccine research, who helped oversee

development of the COVID shot during the first Donald Trump

administration.

The House of Representatives Judiciary Committee in May

wrote in a letter

to Pfizer Chief Executive Albert Bourla that it is looking

into the comments allegedly made by Dormitzer.

The company began to share its trial results on November

9, 2020, just days after Joe Biden won the presidential election

against Trump.

Pfizer has long denied any relation between the timing

of its vaccine results announcement and the U.S. election.

The company and Dormitzer did not immediately respond to

Reuters' requests for comment.

"The allegation that some Pfizer employees worked to

withhold public health information, apparently so as to

influence the 2020 presidential election, implicates substantial

federal interests and requires additional inquiry, which will in

turn inform potential legislative reforms," according to a

statement from the House Judiciary Committee on Monday.
