The report from the Republicans on the House of Intelligence Committee
It was another landmark week in the presidency of Donald Trump. He hosted key U.S. allies Emmanuel Macron of France and Angela Merkel of Germany; but, he also had to weather more turmoil in his Cabinet as well as the ongoing Russia investigation and intensifying scrutiny of his personal lawyer, Michael Cohen.
What might be an extraordinary week for another president has quickly become “situation normal” for the man elected as the nation’s 45th chief executive.
Trump wound up his chaotic week Friday by meeting with German Chancellor Merkel. During an Oval Office photo opportunity, Trump was eager to embrace a report from Republicans on the House Intelligence Committee that found no collusion between the Trump campaign and Russia.
“It was a great report. No collusion, which I knew anyway. No coordination, no nothing,” said Trump with Merkel looking on. “It is a witch hunt. That is all it is. No collusion with Russia, if you can believe this one.”
Representative Adam Schiff, the ranking Democrat on the House Intelligence Committee, issued a statement criticizing the Republican conclusions. Schiff asserted the committee did find evidence of collusion in “secret meetings and communications” between Trump campaign officials and others with links to the Russian government. The matter remains the focus of the investigation led by special counsel Robert Mueller.
Earlier in the week, Trump bonded with French President Macron during a formal state visit that was noted for the warm physical interactions between the two leaders.
“He is going to be an outstanding president. One of your great presidents and it is an honor to call you my friend. Thank you,” Trump told Macron at the end of their joint news conference.
Trump also received more good news this week when his choice for secretary of state, Mike Pompeo, finally won Senate confirmation.
There were, however, some significant setbacks as well, including the withdrawal of Ronny Jackson as the next head of the Department of Veterans Affairs and intense congressional scrutiny of embattled EPA chief Scott Pruitt, under fire for allegedly misspending government funds.
