The Kremlin said Friday it hoped Washington would not release the secret details of telephone conversations between Russian President Vladimir Putin and his US counterpart Donald Trump.

The Kremlin spokesman Dmitry Peskov made the remarks in response to a question about the White House's announcement of a July 25 phone call to Ukrainian President Volodymyr Zelensky that sparked a political storm inside the United States.

Peskov said the publication of confidential details of such contacts was contrary to the general diplomatic tradition, adding that he hoped the deteriorating situation in relations between the two countries would not lead to a similar situation with regard to Russia.

US media have reported that Trump encouraged Zelensky during a phone call to investigate the activities of Biden, who worked for a gas company in Ukraine when his father was former vice president Barack Obama.

Trump is also reported to have linked military aid to Ukraine with such an investigation, which, according to observers, could influence the front-runner for the Democratic presidential nomination in 2020.

Trump denied
Trump, however, denied that he had put any pressure on Ukraine's president, said he was under a false media campaign, and demanded that Democrats be transparent about Biden's money instead of wasting time in nonsense.

The Democratic Party decided to move forward with Trump's parliamentary trial in preparation for his removal.

The House of Representatives, which is controlled by Democrats, will investigate Trump's accusations of seeking help from a foreign head of state in order to discredit his Democratic opponent Joe Biden.

Achieving accountability may ultimately lead to Trump's removal, even though it will be a difficult task for Democrats.

Even if the House votes to hold Trump accountable, it is the Republican-controlled Senate that will take the next step by removing him from office after his trial, and his conviction needs a two-thirds majority in the Senate.
