DES MOINES — Leaders in the Iowa Legislature announced plans Thursday to extend the “pause” in their 2020 session until at least April 30 due to continued concerns over the potentially deadly coronavirus outbreak.Lawmakers, who left the Capitol temporarily on March 17 with plans to restart the session on April 15, said the decision to further suspend legislative activities at the Iowa Capitol building was influenced by President Donald Trump’s directive to set a national social-distancing policy through April 30 that avoids large gatherings and concern over the uncertain outlook for state tax collections that will impact budget decisions for the current and 2021 fiscal years.“The Iowa Legislature continues to follow the guidance of the CDC and the Iowa Department of Public Health.
